Add backup camera to 2014 Tahoe SSV

[EMSTahoe]

So after much forum research, googling, etc I known that my Tahoe is "prewired" for the backup camera mirror. I have triple checked that the blue and white wires are in the mirror connector in the correct pin positions. So the question is where is the connection for the camera at, many say in the drivers side kick panel but it's not there. One guy on a forum doing the same project on an avalanche stated that he found it running down the left side headliner after the harness split at the top of the left a-pilar. So just looking for any advice, I understand how to wire all this. I just want to know where that other input connect is in the Tahoe.

Just so no one is asking, I am a current Texas police officer. That's how I purchased this vehicle new.

On my 2013 Suburban, the wiring does go down the driver's side A-pillar, but then crosses along the instrument panel harness to the passenger side kick panel. There's a separate plug there where it connects to the body harness just to the left of the main body harness plug. Might be the same for the Tahoe.

Ok I'll have a look, thanks

Also here's my build sticker, I have the YE9 code.

Well I found it! I had to drop the headliner and do some exploring. The connector for my Tahoe was in the right hand "c" pillar, just tucked away. I followed the harness from the left "a" pillar, the harness is glued to the headliner.

I made peeled back some of the tape on the harness to make sure that the shielded wire did travel to the rear. It did!



Then I flowed it back and checked the pillars, bam there it was on the right "c" pillar, blue and white wires. It even appears that there is a ground wire on the female end as well. I also located some other harness end but don't know what that is.



Here is the location where it was



So now what would go from this point? Is there an oem wire extension? I know of the one on eBay, but I figured I'm already this far so...

After studying the wiring diagram for the camera circuit a bit, there appear to be three connection points in the chassis. Connector X421, which is what you found at the C pillar. (It's not clear to me in the photo, does the camera wiring terminate there? Or is it connected to another harness?) Connector X209, which is what you should find at the passenger side kick panel (this is meant to be a connector for those who have the Nav screen). And Connector X413 which is supposed to be located in the vicinity of where the liftgate harness connects to the main body harness at the rear of the vehicle under the roof panel. I think if X413 is there as a part of the pre-wiring, then one approach would be to find the correct liftgate harness to retrofit, or to simply extend the camera portion of the harness. Wiring diagram attached.

It terminates at the "c" pillar, there is another end that was with it but that does obviously not fit with the camera connection. I will check the harness near the rear by the lift gate.

Ok so here's where I am now. I extended that harness with the plug, it almost reached the rear hatch area. Did some research via the parts sites and found that there is are 2 harnesses for the lift gate one has the camera wires one doesn't. So I ordered the new harness with the camera wires the plug for the camera matched but the plug that would meet in the roof after it passed from the lift gate doesn't. The new lift gate harness also has these wires in addition to the blue and white ones



I checked my part number for my current lift gate harness and it doesn't match anything anywhere. Just wondering if I'm missing a splitter or something. I know that camera will need to draw power from some source.
