N00b Trailer Wiring Question

ckevroll · April 17, 2011

I recently got a 2001 Yukon SLE and cannot get power to the trailer plug. I had to actually plug the factory wiring into the receptacle because it had never been used. Both maxi fuses (left and right) are in the fuse box under the hood. I have heard that there is a power wire that must be connected under the hood but I cannot locate it. Can anyone tell me or post a picture of where that is?

It's mainly how to hook up an aftermarket brake controller on a late-model pickup, and it also shows the wire that needs to be attached that supplies power to the trailer connector. It might steer you in the right direction.

OK, I'm in there and my power box does not look like the ones shown. Maybe it is an older style but it is a MY 01' Yukon SLE. Im not seeing the wire for power in the harness either...!?

midway down under Step 2 for 'Vehicles without factory installed 7-way'

You need to remove the outer fuse box cover and you will see both the red and the blue wire as in Picture D in the above link

I found it after taking the cover off. It was already wired but the 40 amp Maxi-fuse was not installed. Thanks for the help!
