[bowtiegurl]

Can someone please tell me where all the ground wire locations are on my 2007 GMC Yukon SLT 5.3 l 4wd?

You can download an electrical manual from the GMupfitter site. It contains the above diagram

all over as noted above

Very interesting, I am certain the negative battery cable connects to the front of the passenger side head but that isn't illustrated above.

shows it at the rear but yes it connects to the front right head and a smaller ground on the same harmess goes on the upper right frame rail up almost under the bumper

That diagram shows '03 up, but is not the '07 up diagram. Very similar from what I remember (obviously the pass head ground in slightly different location)

If we are in the 07+ section let’s get the right chart for our friend here

I wonder what clean and dirty mean. I've never seen that on a diagram before

 

[mikez71]

Not sure, I was speculating the clean grounds might have to do with electronics/modules...

Looked it up..

ahh that's interesting.
