Ford F-150 Brake Controller

Installation of a Brake Controller for a Trailer on a 2009 Ford F150

Today we are going to install a Prodigy Brake Controller, part number 90185 on our 2009 Ford F-150, and we are going to use the accompanying brake control adapter and show you how it gets installed. This is a little bit different from previous models. The plug for the brake controller is actually behind this tray right here. What happens is, this panel comes off, and then we get behind the tray - unscrew the tray - and the connection is right behind it. All right, what we are going to do first is go ahead and just take off this panel right here. And it is actually pretty easy. Just give a gentle pull on the bottom and just work your way up. And start on the right-hand side, so that way you can pull it out from underneath this piece here. When you do pull on this, this little panel here will come back toward you, too, and give you a little bit of extra room to pull it out.

There is a wire harness back here for the four-wheel drive, and you have got to disconnect that plug. There is a simple tab on top you just squeeze it down just like a tail light assembly. This compartment here gets unscrewed from here and here. We just undo these two screws and pull the whole thing out. OK, pull this out. You do not have much slack, but there is our connection right here, built into the back of the tray. Unclip it, and then we can install our brake control adapter. You can take the whole assembly and actually run it behind the plastic down out toward the bottom of the dash, where we are going to install our brake controller. And at this point we are going to put our trim panel back together.

We can mount our brake control down on the bottom now. There a few different ways to install the brake controller. You can mount it on the dash, like so. There is also a little edge on the bottom here. It is kind of on the low side, but it does keep everything a little bit out of the way, too. It is personal preference on this one. We are going to mount it on the bottom. We will mount our brake controller bracket up to this plastic and then we will just run our screws into it. We will go ahead and snap in our brake controller. All right, our next step is to go ahead and take our wires and hide them up underneath of it. All right, and the install of the brake controller is complete.That covers our install of a Prodigy brake controller, part number 90185 on our 2009 Ford F-150.

Questions and Comments about this Video

I have an 06 F/150 FX4, it has the towing package with the plug for the 4 flat and the 7 round plugs. Which harness do I need?

For Tekonsha controllers, you'll need the 3035-P harness for a 2006 Ford truck with a factory 7-Way. Below is a link to all our controller bundles for a 2006 F-150 with factory 7-Way. If you already have a controller, I've also included a link for just the harness.

Today we are working on a 2004 Ford F-150. We are going to be installing the Tekonsha Prodigy P2 brake controller, part number 90885-3035P. Our first step in installing our brake controller will be locating the plug to plug our connection into on the manufacturer side. Here, up under the dash above the brake pedal, there is a gray plug that will match up perfectly with our wiring harness. Now that we have our wire harness connected to the manufacturer harness, we are going to go ahead and mount our brake controller. 0:36

Diagnosing a Brake Controller Problem

Alright, today on this 2009 Ford F-150 we are going to diagnose a brake controller problem. Now we can use these steps on any brake controller that is on the market to verify if it is working or not. Now our brake controller is already telling us that it has an error message. It is flashing an Er on top. Usually it means an internal problem. We tested our trailer so we know it is good. So, it is not that. So first off we will make sure we have a constant 12 volt power supply. We will check the black wire first. OK, we are good there. Now we will try our red wire for our brake signal. OK, that is good there. Now we will try our blue wire and that will be our output. So we should have output on this wire whenever we hit the foot brake or the manual override. OK, we get nothing on the foot brake and nothing on the manual override. So definitely the error is internal and this brake controller does have to be replaced.

Trailer Brake Controller Installation - 2001 Ford F-150

Today on this 2001 Ford F-150 we are going to install part number 90195-3035P. This kit will include the P3 brake controller and the adapter cord that will plug into the truck. Alright, we will start off with our adapter cord first. This is the end that will plug into the port. It is right next to the diagnostic port. And we just snap it into place. Alright, we have it plugged in. Let us go ahead and test the wires and make sure everything is working. Our black wire is going to be our 12 volt power supply. That is good. And red is going to be our stop light switch. OK, and white is going to be ground. And blue we have output to our trailer brakes so we do not have to test that. So it looks like our plug is good. 0:45
