How to Install a Trailer Brake Controller Installation - 2003 Ford F-250


Today on our 2003 Ford F250 well be installing the Tekonsha P3 proportional brake controller with a Ford adapter, part #: 90195-3035P. To begin with lets go over a couple of different mounting options that we have them on our new brake controller. You can either use the traditional metal style, or you can use the plastic style that allows you to remove the brake controller whenever you want to. In our particular install were going to be using the traditional style metal bracket. For the hardware well be using to mount it, well be using two machine style screws to attach the brake controller to the metal bracket that will go in each of the holes, one on each side. Now to mount the bracket on the underside of the dash well be using the two self-tapping style screws to hold the bracket to the underside of the dash.

Now lets go over the wiring adapter that well be using. The brown end is the end thatll plug into the factory wiring harness up underneath the dash. The other end that has the four flat style will be connecting to the back side of the brake controller. As you can see here, when you plug the wiring harness into the back side of the brake controller there is a locking tab on the top side and when you push the wiring into the back of the brake controller you want to make sure that it fully locks into place and you do hear it click. Now lets go ahead and go choose a mounting location on the lower section of our dash.

As you can see here, this vehicle has a few other options already installed. Were going to put it down below some of the other accessories that are already in the vehicle. Well use a small drill bit to put two small holes in the dash to make it easier for our self-tapping screws to go in the dash. Before drilling into the dash you want to make sure that theres nothing behind it that could be damaged. Now that we have our two small pilot holes well go ahead and put our two self-tapping screws into the dash, holding the metal bracket in place.

Now that weve got our bracket in place well need to remove the panel here, just below the steering wheel, to gain access to the factory plug. To remove the panel you simply turn these four locations about 90 degrees and then you can pull the panel off. Right up here underneath the dash is where the plug that well be tying in with is located. Next well go ahead and take the wiring adapter, were going to rout it underneath the dash up to where our factory plug is. Youll how on one side of the plug theres a wider portion, so we need to make sure that we line this up properly.

Once we have the plug lined up well go ahead and snap it into place, again, making sure that the tabs fully lock into place. Next well go ahead and rout our wiring down to where our brake controller will be mounted. Well then go ahead and plug the wiring harness into the back side of the brake controller, again, making sure that the locking tab is fully seated. Next, well take our two machine screws and connect our brake controller to the metal bracket. Once we have these two tightened down well go ahead and button up any loose wiring that may be up underneath the dash by using a couple of zip ties. Now lets go over a few functions of our brake controller. The slide at the bottom of the brake controller is the manual override. This brake controller does allow you to switch between electric and electric over hydraulic setting. You can also change the brightness, the contrast or even the color of the background on your brake controller. The up and down arrows on the left hand side allow you to adjust the power output as well as change other functions of the brake controller. With that, thatll complete our installation of the Tekonsha P3 proportional brake controller with Ford adapter part #: 90195-3035P on our 2003 Ford F250. .
