I have a 2004 Chevy Tahoe Z71. Bought a Hopkins Agility Brake controller and the matching harness. Everything works at the 7 way connector. But I have to use the manual override to get the brakes on the trailer to work. I have power to the red wire from the controller to the harness, the harness to the fuse box, but nothing at the 7-way. Any help would be greatly appreciated.
