Last issue: Head Unit switches to "Video in"

[Chrismnj]

what you doing now is plugging your camera to video input instead of rear view camera input, thats why when out of reverse your screen stays on video input, you cut power from your source "rear camera" by selecting a different gear than reverse and no signal message comes up

hmmm....I definitely plugged the adapter into #16 (rear camera input).
But the link to the other adapter is interesting.
Seems like the yellow wire is just like mine.
but the black seems to be on the other side...
AND the other two cables just bypass the pins and go pack to the harness again...maybe thats the cruncher?

unfortunately you cant see the rear of that harness on the link...

Try it may work, just make sure this harness fits your year.

I was going nuts with my setup I am running 4 different cameras, front, rear, left and right (which activates with blinkers).

Does anyone have a pin-diagram for the harness that comes ot of the dash for the stock backup cam?
(usually I want to know what I am doing - but if not...I will trial and error)


When I look at 2011 Yukons the harnesses are all the same like mine without that jumper cable from your link.
Maybe thats because of some Denali-trim??
I definitely have more cables in that harness from the dash...

In this picture it looks like the jumper cables just crossover the pins:

That not exactly my harness, but it also mitght help.
At least I see that there is a Pin "backup lamp relais control".
Looking at the adpater with jumper cables, it looks like they just ground it to Pin5.

 

[Chrismnj]

yeah, don't forget RCA has + and - , so maybe you missing ground

 

[Chrismnj]

that pin is from silverado, but should be same color code.

 

[tengelman]

..there are no colors on that pic



No „matching“ colors i meant.....mine are different...
Looks like its gonna be trial and error...
