Hot wire to trailer.

[royalglen]

I got the trailer towing package and integrated brake control on a 2011 Chev 2500 HD but the hot wire to the trailer is not conected. There is a tag on a wire at the fuse box marked "aftermarket trailer wire". Anyone know what to do to hook it up. Please advise.

Solved my own problem. Was at the dealer and fixed the power to the trailer plug. The wire marked "aftermarket trailer" is for brake control for hydralic brake controler.
