GM Camera Support

Most installations will incorporate a rear camera of some sort, whether it means wiring in the factory camera that displays on the mirror or factory navigation screen, or adding an aftermarket tailgate, license plate or drill-through style camera. The tips below are designed to help with these different scenarios.

Although we try to anticipate most questions (and solutions), your situation may not be covered in this guide. Feel free to call us if you are having trouble installing or wiring your camera – we’re here to help.

Some of the methods shown below may be challenging if you are not mechanically or technically inclined! In order to accomplish these modifications, we assume you own basic tools such as crimpers, solder, volt meter, etc. and can identify the harnesses or wires called out in each method. IF YOU ARE NOT CONFIDENT OF YOUR CAPABILITIES OR TOOLS, PLEASE DO NOT ATTEMPT THESE MODS! Overall, it’s much easier and less expensive to pay a professional installer to do what you’re not comfortable with rather than blow up an ECM or melt wires in your vehicle…

If your vehicle has the FACTORY rear camera already installed and playing on the factory mirror monitor (normally 2008-up ONLY), you can wire your factory camera to the GM2007PRO. There are two places you can tap into the wiring for the camera: the left kick panel area or above the left I/P Junction Block (large black plastic cover on the firewall between the e-brake and foot brake pedal). The easiest way to identify where to go to grab these wires is to identify the wire colors in the back of the mirror plug.On the back of the factory monitor mirror is a 16 pin plug – unplug this plug and look at the back of it (wire side). There will numbers printed on it showing Pin 1,8,9 & 16. Looking at the back of the plug, Pin 1 is at upper right and Pin 8 is at upper left. Pins 6 & 7 are the camera wires.

If pin 6 is WHITE and pin 7 is DARK BLUE, follow METHOD 1 below.

If pin 6 is GRAY/BLUE and pin 7 is GRAY/ORANGE, follow METHOD 2 below.


This is by far the most common arrangement found in Silverado/Sierra pickups. The factory camera plug is located at the top of the left kick panel (the plastic panel to the left of the driver’s foot).

2008-11: Plug has five wires on BOTTOM OF PLUG (towards floor) – See Fig. 1
2012-13: Plug has five wires on TOP OF PLUG (towards roof) See Fig. 2

No matter what year truck you have, the process is the same: to wire the factory camera to the GM2007PRO, connect a single RCA lead to the rear camera input on the GM2007PRO, then route the other end to the driver’s kick panel. Cut off the end and strip the insulation exposing the outer bare copper wire (shield) and the center conductor. Attach the RCA’s outer shield to the blue wire and the RCA’s center conductor to the white wire as shown below:


There is another, less common version of camera wiring in the 2009 to 2013 Silverado/Sierra, with the camera leads contained in a white plug that is located above the left I/P junction block on the driver’s side firewall. On this plug, the gray/blue is video positive (connects to center conductor of RCA) and gray/orange is video negative (connects to RCA shield/braided wire):

Aftermarket Camera Power and Ground Connections

Since the GM2007PRO gets its reverse trigger through the databus of the vehicle, it is not necessary to wire a reverse trigger lead in GM vehicles. All that’s required to add a backup camera is to add the camera, power it up, plug in the RCA video output lead to the GM2007PRO reverse camera input RCA, and enable the camera in the menu.

When wiring an aftermarket backup camera, keep in mind that the GM2007PRO allows access to the camera while driving, so if you are planning on using this feature, it’s important to wire the camera to an accessory or ignition power source.


The easiest place to get power (in the Silverado/Sierra/Tahoe/Suburban/Yukon) is at the left I/P Junction block, which is under the large black plastic cover to left of the foot brake pedal on the firewall. When you remove the cover (by pulling outward on both sides while pulling straight towards you), you will see a number of “ports” in the junction block with various plugs plugged into them. Your truck may differ slightly from the photo shown below, but the pin locations shown should be the same for almost all GM trucks that we’re aware of.

If you are planning on using your camera ONLY while in reverse, we recommend connecting the 12v power lead for it to the reverse wire (dark blue wire in the upper right port in the pictures below), which will power the camera on ONLY while the vehicle is in reverse and will not allow camera operation while moving. Ground for the camera can go to any metal point on the truck, or you can grab it at Port X14, Pin 1 (GROUND) in the pictures below.

If you are planning on using your camera while the vehicle is in motion, the camera needs to be powered from an accessory or ignition circuit. In this case, the camera’s 12v positive (red) lead can be hooked to Port X14, Pin 7 (IGNITION) or Port X14, Pin 8 (RAP ACCESSORY) NOTE: the ACC circuit on Pin 8 supports a maximum 2 amp draw only! Use this only if you are certain that your camera will draw less than 2 amps – if uncertain, we highly recommend using a relay triggered from this circuit to route a higher amperage source of voltage to your camera or other accessory.  Ground for the camera can go to any metal point on the truck, or you can grab it at Port X14, Pin 1 (GROUND) in the pictures below.

If you have purchased the CS-GMTRB tailgate camera kit, download the CS-GMTRB installation manual or watch the installation video below to get more detailed information that will help familiarize you with the installation process.

To start the installation, first remove your old tailgate bezel – Use the 13mm socket wrench to remove the bottom bolt of the tailgate latch – YOU DO NOT NEED TO REMOVE THE TOP TWO 13MM BOLTS. Pull the tailgate handle up out of the way with one hand and firmly grab the plastic bezel with the other and give it a good tug. Be careful, because it has a tendency to bust a knuckle on the way out. To install the camera, you will simply snap the new bezel in place and reinstall the 13mm bolt, but first you will need to run the camera cable out of the tailgate.

All trucks have drain holes in the bottom of the bed, and the camera harness is small enough to pass through the center drain hole. Pass a fish tool of some sort (a coat hanger works great) through the center drain hole up to the handle area, then tape the camera lead to it and GENTLY pull the cable through the drain hole. All 2010 and newer trucks already have a 1 1/4″ hole in the back of the bed, and if yours has this, simply pass the camera cable into this hole and under the bed in preparation for connecting and running the extension harness. If you do not have a hole in the back of the bed, you have two options: drop the camera cable UNDER the back of the bed, or remove the tailgate and drill a 1″ hole into the rear panel of the bed and snap in the supplied plastic grommet, then pass the camera cable through to the area under the bed. Pull the excess wire slack under the truck. Slide the wire loom over the wire and up through the tailgate so the exposed portion between the tailgate and box is protected (shown at bottom left). Tape the loom in place and zip-tie the camera cable to an existing vehicle harness, leaving enough slack to operate the tailgate properly (center).

To insure a secure, watertight connection (especially important if you launch a boat on a regular basis), source some dielectric grease and coat the male connector with it prior to plugging the male plug into the female socket of the extension harness. Connect the male and female ends of the camera harness (be careful when plugging in the camera connector – it has a keyway and only fits one way!), then tape or heat shrink the connection to seal out moisture. Run the pre-loomed camera harness alongside the factory harnesses on the left side frame rail toward the front of the truck, using the included zip ties to secure it.

The easiest place to enter the cab is through the parking brake cable grommet on the driver’s side floor near the front left corner of the driver’s seat (right). To access this grommet, remove the driver’s side sill plate and peel the carpet back far enough to see the top of the grommet. Carefully pop this grommet out (it helps to push from below). You can pass the cabling through this grommet two ways: make a “X” cut in the hard rubber and pass your cables through, or cut through the outer hard plastic rim, then split the rim to pass your cables through. We suggest splitting the rim, which will allow you to pass the cables into the cab without worrying about damaging the RCA end when trying to force it through the very stiff rubber grommet.

Once you have passed your cables through the grommet, seal the grommet with some RTV (silicone) sealant to insure no leakage (below left). You can split the RCA output cable and the power/ground wires and pass the signal wire to the radio and plug it into the rear camera input female RCA. Pass the power and ground wires (red is power/black is ground) to the Left I/P Junction Block (under the square black cover to the left of the foot brake). Remove the cover by pulling out on the sides, then pull straight towards you. The camera’s red wire (power) can be wired to the dark blue REVERSE wire, the ignition circuit on Port X14 Pin 7, or the RAP accessory circuit on Port X14 Pin 8 (as detailed in the previous section above) and the camera’s black wire (ground) can go to the GROUND terminal shown below (below center) or to any “bright metal” in the truck, such as under a nut or screw.

Once you enable the camera in the menu on the GM2007PRO, start the truck and place it in reverse – it should display automatically. You can also choose to mute the audio system when in reverse in the settings menu.

NOTE: Duramax diesel trucks need to be running in order to power the reverse circuit.

If your vehicle came with the factory camera that displayed on the mirror or factory navigation radio, the GM2007PRO allows you to use it while driving, but you will need to change the factory camera power source, since it is normally only powered while in reverse.Depending on the type of vehicle (truck or SUV) and type of original factory display (mirror or factory navi), this operation may be done different ways:


If your vehicle came with the factory camera that displayed on the factory navi radio OR if your vehicle came with the factory mirror display (AND YOU DO NOT WANT TO RETAIN THE MIRROR DISPLAY OR YOU WANT TO MANUALLY TRIGGER IT),  use this method.

(1) Identify the blue wire in the upper left connector (X11, White plug, pin 5) at the left I/P junction block as shown below. (Note: the left I/P junction block is under the black plastic square cover to the left of the foot brake). Verify this blue wire goes to 12v when the truck is in reverse.

(2) Unplug white “X11” plug in the upper left, then de-pin the BLUE wire in the pin 5 location (factory camera power as shown below, center). Release the connector by releasing the red keeper then lifting up on the tang that retains the female connector in the plug.

(3) Remove this BLUE wire from the White X11 plug and insert it onto the the IGNITION pin (X14 Pin 7) in the diagram below.

(4) NOTE ON FACTORY MIRROR DISPLAY: To turn off the mirror display (which will now be on full-time with this modification), remove the DARK BLUE wire in Pin 9 location of the mirror harness (shown in next section), or add a toggle switch to this wire if you want to use the mirror display on-demand.

If your vehicle came with the factory camera that displayed on the factory mirror display (AND YOU WANT TO RETAIN THE MIRROR DISPLAY OPERATING ONLY WHILE IN REVERSE),  use this method.

You will need to source a standard automotive “Bosch” style NORMALLY OPEN relay, five female “.250” spades (for relay), two butt connectors (to extend factory wires), two “.110” female spades (for power/ground connections at junction block), short length of wire and electrical tape. NOTE ON RELAY: Bosch style relays come in two types: normally open and normally closed. You can tell the difference by the numbers assigned to each terminal. The normally open relay will have 5 terminals labeled like this: 85/86/87/87A/30. Normally closed relays will have 4 or 5 terminals labeled like this: 85/86/87/87/30

(1) Identify the blue wire in the upper left connector (X11, White plug, pin 5) at the left I/P junction block as shown (above center). (Note: the left I/P junction block is under the black plastic square cover to the left of the foot brake). Verify this blue wire goes to 12v when the truck is in reverse.

(2) Using the picture below as your guide, strip back some of the black tape on the “X11″ harness, then cut the BLUE factory camera 12v wire as shown below. Extend both sides of this wire by 6-8” and add .250 female spade connectors to the ends. Connect the wire that comes FROM THE JUNCTION BLOCK TO PIN 30 on the relay and the wire that GOES INTO THE HARNESS TOWARDS THE FLOOR TO PIN 87A on the relay.

(3) Connect three more short pieces of wire to the relay on pins 85, 86 and 87A. 

Connect 87 to pin 5 of port “X11” – IGNITION
Connect 86 to pin 1 of port “X11” – GROUND
Connect 85 to the DARK BLUE wire in pin 8 port “X10” – REVERSE

If the relay is wired correctly, the camera will be displayed on the GM2007PRO and on mirror display in reverse while allowing you to switch to the camera on the radio while in motion.

GM Mirror Monitor Trigger If you don’t want to have the factory mirror display the camera after you have wired the camera output for full-time use on the GM2007PRO, you can disable the display in the mirror very easily. The trigger lead that turns on the mirror’s display is the dark blue wire in Pin 9. You can either cut and tape this lead, or preferably, unlock the tab on the bottom of the factory plug and remove the pin from the plug (so you can reinsert it at a later date if you ever remove the GM2007PRO). If you remove the pin, just tape it to harness so it’s not flopping around.

Alternatively, if you want to be able to use it on demand, you can set this wire up on a toggle, activating it when you want to use the mirror monitor.

If you want to get really tricky, we can show you how to add a front camera (or trailer camera) and have it display in the mirror!

You may have a mirror that has no easily accessible plug in the kick panel location to get the camera’s output from (see factory camera plug info below). In this case, you can always go to the back of the mirror to tap into the camera video positive and negative wires. These wires will be in pins 6 (usually white or pink) & 7 (usually blue) in the plug on the back of the mirror – you can also grab them further up the harness under the short overhead console – they are usually wrapped in blue foil further up the harness under the tape:
Factory camera wires in foil wrap – White is video + & Blue is video – “T-Tap” connectors added and connected to RCA cable Once connections are made, tuck the cables into the existing console hole
On the Tahoe/Suburban/Yukon, the factory camera plug should be located in the right (passenger side) kick panel area (we have not verified this location – if you do, please snap a photo and send to us) and have the following pin assignments:
If you are replacing a factory GM navigation unit and have the factory camera that displays on the navi screen, you can still use that camera output on the GM2007PRO. When you remove the factory navi, you will have one plug that does not have a mate on the GM2007PRO harness: the BROWN “X4” connector, which will have three or more wires in it. In this harness, the camera leads are the wires in pin locations 6 & 7 (see schematic on left below).

NOTE: If you have the factory Centerpoint system, you will use the subwoofer harness provided with the GM2007PRO on the X4 connector, but it will not have the camera leads in it – you will still have to do this modification.

To hook up the factory camera, you will cut off one end of a short RCA cable (not provided with GM2007PRO), then strip the outer insulation and separate the center conductor from the outer copper braided wire, then connect the RCA center conductor to the pink or white wire in pin 6 of the BROWN X4 connector (this color will depend whether your truck has RPO code “Y91” – found on RPO code sticker in glove box) and connect the RCA braided outer wire to the lt. blue wire in pin 7.

The situation may occur when you pull the factory NON-NAVIGATION radio that you’ll find FOUR factory connectors on the back of the radio (with RPO codes UQA or UQS & UK6). When you have the factory backup camera system, the camera wires MAY also be included in the BROWN “X4” connector at the back of the radio as shown in the schematic (above right). HOWEVER, THIS IS NOT GUARANTEED – WE HAVE SEEN VEHICLES WHERE THIS IS NOT A VALID CONNECTION POINT.

If the camera is wired to this plug, the camera can be wired to the GM2007PRO with the center conductor of the RCA connected to the pink wire in pin 6 and and the shield of the RCA connected to the blue wire in pin 7:

If you are not comfortable cutting or tapping the wires discussed above, Camera Source has adaptors that can make the camera connection more “plug and play”:

Grille Mount:

With the Advent CAM-500 camera, front camera installations have never been easier – the pictures below show the front camera installation on our own 2011 Tahoe, and mounting this camera installation took less than five minutes. All that is required is to wrap the threads with a couple layers of electrical tape and force the camera into one of the openings in the crosshatch grille. It will be a VERY snug friction fit, that will be very stable and gives a great view over the front bumper.

If you already have a rear camera, the easiest way to display the front camera on the GM2007PRO is to simply plug it into the yellow AV2 input video RCA, then simply activate the AV2 source button on the main menu and you will have access to the front and rear cameras from the menu bar at any time:
If you are using the AV2 input for another source like rear headrest input or a CRUX WVI, then the easiest way to display the front camera will be use a switch to toggle the rear camera input between the front and rear cameras. This can accomplished using a toggle switch and a standard relay as shown (BELOW LEFT).

This process involves switching both camera’s video positive leads (the center conductor of the camera’s RCA cable) through the relay and out to the radio. It can be done by cutting and soldering the leads right onto the relay, but we strongly recommend putting the relay together using female RCA female extension cables for all connections (commonly available as a (1) MALE to (2) FEMALE RCA “Y” adaptor – simply cut off the male end and you have two female leads) so that both camera output wires and the jumper to the GM2007PRO can be done without modifying the camera or radio leads themselves (BELOW RIGHT).

Using any standard single pole, single throw (simple on-off) switch, wire it as shown so that you’re switching ground to the relay to turn it on and off (since there is 12 volts (ACC) on the other side, switching ground will turn it on & off)

In this arrangement, with the relay at rest, pins 30 and 87A are connected, leaving the rear camera connected to the rear camera input on the GM2007PRO as it would normally operate.

When the switch is flipped, the relay turns on and you are now connecting pins 30 and 87, sending the front (or second) camera’s video output to the rear camera input of the deck, allowing you to view that camera.

All RCA outer wires (usually bare copper) should be twisted together and crimped or soldered.
