Trailer Brake Controller Install Harness Location for 2010 Ford F-250

Updated 06/12/2017 | Published 06/10/2017

Question:

I have a 2010 Ford F-250 the plug behind the dash that plugs into the trailer brake controller has no power so I trace the wire and the other end is not hooked up. Is there a place that it plugs into or is there another harness I have to buy to hook up my after market brake controller

Is it possible the harness you found is actually an aftermarket install harness that's just not plugged into the truck? If you found the Ford harness it really shouldn't be possible that it's unplugged as it is supposed to be hardwired to the truck. The install harness normally used with your 2010 Ford F-250 is the part # 3034-P which does plug in behind the dash.

I attached a picture that shows where this harness normally plugs in behind the panel on the dash.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well.
