Have a 2007 Suburban and trying to hook up the trailer brake (note it has a tow package and has the four wires under the dash to hook up).

I hooked up the trailer brake and nothing (note: hooked up to trailer and no power). I disconnected the four wires to the controller from the truck. I checked the readings to each wire with the truck on...checking the red (battery positive) and the white (battery negative) there was no power. Is there something else that needs to be done? the fuses are fine. thanks for the help.

Search the Tahoe forum, this was talked about a few weeks ago. You need to connect the wire that is located between the UBEC and front fender to a stud located under the cover of the UBEC. You will find the answer there. I will check back here later to see if you found the answer.

Thanks for the info. Found the post and it was exactly what I needed. I have everything hooked up and tested and it's good to go. Thanks again!!!
