Trailer Brake Controller Installation - 2003 Ford F250

Installation of a Brake Controller for a Trailer on a 2003 Ford F250

Just to give you a reference point, this is the top, right here of the gas pedal, so basically its across up on this pillar here. While were here well plug in our brake controller adapter and that will be part # 3035-P. Now we can plug the other end of this into our brake controller after we install the mounting bracket. Next well mark our bracket for positioning, well just hold it up here on this bottom edge where its nice and flat. In this corner right here, well just make a small dot for reference and then well put our first screw there. Afterwards well put our brake controller inside and eyeball it to make sure we get it straight. When we have positioned the way we want it, we ll make our secondary screw install here. Okay at this point we can simply install our adapter cable in then well just mount right here. We have the brake controller installed now, the last thing we do is take the wires and zip tie them into a safe position and all we have to do is test.

Now well check it, obviously we have two lights going here, one lets us know we have power going to it and the other one is the boost setting. What we do next is use our manual override and it shows NC which means there is no current going to it, which is obvious we do not have a trailer hooked up to it. Now well get our tester and try it out that way. Once you have plugged your test device in, you can see here we have a C which says its connected. Well test the manual override and it spits out voltage. It looks like its a scale of 1-12, well check the dial to make sure it works, move it all the way down and back up. Leave it in the middle at about 6, which is a good way to test to fine tune it to what load situation you have on your trailer. That covers it for your install of part # 90185, the Tekonsha brake controller and the adapter cable 3035-P.
