I obtained a new 2010 GM truck tailgate handle with the built in back up camera to connect to my aftermarket radio and is a direct fit for my tailgate.

My only issue was I didn't know what the pinout for the camera was.  There were six wires for this camera and being it was so new I could not find any diagrams for it.  After a few tries I figured out the pinout and thought I would share.

Red - 12V positive

Black - 12V negative

Yellow - Video out +

Brown - Video out -

White - Shield for video wires (yellow & Brown)

Blue - Positive turn on lead (sending 12V+ to it turns on the camera)

I tied the brown wire and the shield wire together and then soldered an RCA end onto the wires.

2010 avalanche has only 4 wires.  If you cut the grey harness a few inches from the camera, it contains 4 wires.  Red Black White and a shield.  If you look at the plug 8 inches down line where it plugs to the tailgate harness the wiring is a bit different.  Red Black White and yellow.  On the plug white is shield and yellow is video.  I cut the grey cable in order to be able to reconnect if needed, in that harness white is video and shield is shield.

Spent the morning installing a pac piece into an OEM  nav unit, only to find out from PAC that the radio they ordered was already programmed to accept a back up camera.  Removed the pac unit from the deck and had to wire the camera to the brown plug that has a GREEN / WHITE wire at pin 5.  Pin 6 is video and pin7 is video ground.  2010 Avalanche integrated back up camera works great following instructions from above post. 

2 back up cameras in 2 days reminds me that I am too old to be sliding around on concrete floors.
