The plugs on the cable side have been damaged but the plugs on the “boxes” are fine, I can remove the fakra plugs and hold the cables in place and everything works just fine so I am hoping I can just replace the cables. I will look at the websites you suggested, That might be just what I need. I looked all over for a schematic for this truck but wasn’t able to fine one. Thank you

I have a 2017 Duramax High Country that was stolen and has now been recovered. When it was stolen they removed the touch screen radio and unhooked the antenna for the OnStar/XM/Nav. However when they did this they just yanked the cables apart rather than pushing down the tab and simply unplugging it. Now my GPS, XM, and OnStar do not work and I need to replace the cables. Can anyone tell me where they route to? I can get new cables to plug in behind the touch screen but I do not know where they plug into on the other end. I tried to trace them but the go deep in the dash and are wrapped up with other wires in the main harness. I know "A" connects to "A" and is for the XM radio The "B" cables plug into the "B" plugs but I am not sure which one goes to which I need to know where each of these 3 cables routes to so that I can unplug them and replace them I know that "C" is for the AM/FM antenna, which is fine, I just unplugged it for the picture because it was in the way, but I do see any wires for the plugs in "D," should something be plugged in to these or were they empty from the factory? Any help would be greatly appreciated. Thank you img_5724 EDIT.heic
