RE: 2012 Yukon not seeing trailer connected
I don't know if the previous owner did, but it looked like none of the 12V leads were hooked up.
The two big fuses for the studs are in place, and I have 12V to each of the studs.

2012 Yukon not seeing trailer connected
I have the factory integrated brake controller,(JL-1) this is the 1st time it's being used as I had to connect the red wires to the studs.
Fuses are good, I have 12V at the studs.
I have 12V at the brake control relay or module located above the spare tire.
The blue wire is good between the module/relay to the 7-pin, and both sides of the 7-pin are clean.
No stored codes.
Trailer works on another vehicle, and the Yukon still doesn't work on a 2nd trailer.
I have also tried a new GM gain switch and module, still no change.
No error messages, but the Yukon still won't recognize when a trailer is connected.
Curious if anyone has dealt with this.
