' 07 - getting power to trailer brakes
I'm desperate and need help. I'll be towing a 30' travel trailer. Actually already have once, only a short distance but without trailer brakes working. I installed an execuhitch and have a Prodigy RF brake controller. All my marker, brake and turn signal lights are working on the camper. I cannot get the blue wire that powers the trailer brakes to work, thus making pairing the prodigy controller to its power module impossible. I know it works because I've paired it with another vehicle to be sure. All I'm looking for is where I can tap into that will send signal to the 7 way plug that the brakes are being applied. Fuses 70, 71 and 72 are useless. Can anyone help me please?

If it is not working as it should, you probably need to have the rear SAM looked at.
Are you using a factory wiring harness?

Where does it connect?
To the SAM?
What does Execuhitch say about the issue.
I do know some early GL's had the brake controller connection near the rear SAM instead of under the dash like later ones.
