Anybody know which wire on my 07 Yukon and where it would be located would be "hot" when the "tow mode" button is pressed? I would like to tap into the "hot" side when the button is put into tow mode and have no 12v when in normal driving mode. Any help is appreciated.
Thanks

Those are not the ones I am looking for. Those go to the brake controller, large red is for the 12v, large blue is for the electric brakes, small white is for the ground and small blue is for the stop light switch (used on some controllers). I am looking for the wire that goes to the Tow/Haul switch in the end of the shift lever that activates that tow mode and the orange light in the dash when pressed. Probably will need a wiring diagram for the wires coming out of the steering column?
Thanks
