Paragon,

Right you are. There is NO difference with the fuse added.
The controller has a light that lights when I use manually but does not light
when I push on brake pedel???

Just thought I'd mention tha tthe Trailering Brake Harness that Hummer sells will not work on '06 and later models unless you change the wiring on them. Don't know if they started making these for the later models yet. I showed the problem to my dealer and they were unaware of the issue.

Then it is the feed from the vehicle's brakes that is missing.

Tomp,

Well I have an 06 so that might be the problem!

What did you have to do to make the fix ?

Thanks
Craig

[PARAGON]

Wow, just stupid. They had the same problem with our '03s, which is part of the reason why mine is wired up differently.

You need to figure out which wire coming out of the Brake controller is the wire for the Brake feed. That wire needs to match with, IIRC, a light blue wire.

PARAGON,

Well crap !

I'll see if I can determin which wire.

To be continued

(controller) the black is positive and the white is negative. The blue on my 03 is hooked to one of the blues under the hood . I just noticed that i have two blue wires dead headed up to the fuse box under the hood. I hooked my blue controller wire to one of my blue wires under the hood and i have trailer brakes. I can take a pic if that helps you. Its prolly all different on a 06.
The moral to the story. I think your blue wire has to be hooked to the blue wire in your harness and you will have brakes. when pedal is applied.
