Electric Trailer Brakes ???

[BLKH2FLA]

I am hooking up electric brakes for the trailer and have the manual activator connected in the cab and when applied it applies the trailer brakes. BUT I have no trailer brakes when using the brake pedel. I looked at the fuse box under the hood and there is a fuse in the spot for electronic brakes I think it was labeled (rdl ) in the manual.

What am I missing ??

Is your electric brake controller , pendulum type or brake light type (inertia)? It sounds like it is the brake light type that will come on when you hit the brakes but need to know which one it is first . doug

It is brake light activated and has a squeeze type slide to operate manually

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?

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.
