Re: Electric Trailer Brakes ???
My wifes gone now with the hummer , so i cant go look yet. But do you have two wires going to the pos & neg of battery? Then one to a hot wire on the end of the brake switch. I think in the fuse box under the hood there is a blue wire that is just sitting there that needs to be plugged in to make the connection to the back of the truck. Does any of this sound familiar? doug

If he has braking upon moving the slider, then the wire under the hood should be hooked up.
BLKH2, do you have any kind of indicator LEDs or lights on the controller?
If so, do they activate when you mash the brake pedal?

Re: Electric Trailer Brakes ???
Paragon- yup your right he is hooked up ,, ,, i had a brain fade.
He must not be hooked to the hot side of the brake light switch. In one way or another.

Yeah, I ended up custom wiring all of my stuff so I have no idea of how "it's supposed to be."
But it does sound as though the controller is not getting any signal from the vehicle brakes.

Re: Electric Trailer Brakes ???
I think I got it figured out!
I found info that says a vehicle without the TP2 auxillary battery needs a
40 A fuse in the ( stud#1 ) location in the under hood fuse box.
( note: this fuse is not needed if you have 2 batteries )
I will check on trailer today and let you know.
Thank you for your time and your help in troubleshooting my problem.

Craig,
I hope it's that simple. But I'm not sure that it is. That would be the power supply to the brakes. If you are getting braking upon moving the slider, then you have power. Stud 1 doesn't have anything to do with receiving voltage from the vehicle's brakes.
I think someone else just last week or so had a similar problem but they were not getting any response back out to the brakes and it was because there was no fuse at stud 1.
