Anyone know where the reverse wire is for a 99 GMC Yukon? This is the OBS.

Thanks!

Yea its the positive wire that leads into the reverse light on the back of the car.

Wow lol obviously. I was asking for the location under the dash. I think I found it. Green wire in the harness to the left of the steering column.

It is a light green wire in the box (with a black cover and plastic nut) that sits just left of the break pedal.

No need to catch the wires all the way at the back of the truck.

Thanks man, I'll check it out this week.
