My solution to connecting an electronic brake control (PowerStop) to the H2, after getting no where with the dealer, is to find the necessary wires myself and bypass the off-road harness. In the 7-wire connector at the rear bumper, all the wires are fine except the variable-voltage red wire that should connect to the controller. Does anyone know where I can locate the other end of that red wire under the hood or under the dash? Thanks.

By the way, I also think that GM should cover this business in a professional manner. My 1989 Expedition came with the harness, a plug under the dash and a set of instructions. That worked beautifully.

Why do you want to bypass the prewired system. All you should need is a GM adapter harness ($10-15.00) and plug directly in the harness under the driver-side dash. If you have factory off road lights, it should be the same harness(just unplug or rewire). The red wire you mention sounds like a power wire for trailer accessories, ie: interior lights, etc.
good luck
