Video Brake Controller Install 2001 Ford F150
Trailer Brake Controller Installation - 2001 Ford F-150

Video Transcript for Trailer Brake Controller Installation - 2001 Ford F-150

Today on this 2001 Ford F-150 we are going to install part number 90885-3035P, this includes the Tekonsha Prodigy P2 brake controller with the Ford adapter. On the back of this vehicle we are going to install part number 118242 from Tow Ready. The first thing we need to do is find the port for the brake control package. On this year Ford it is pretty easy, right next to the data port here. Right to the left of it you can see it right here. So our adapter cord we will plug that into the port right here. Now we will plug this other half in the back of the brake controller and now we will find a spot for our bracket. A nice thing about the P2 brake controller is you can mount it vertical so you get more choices in mounting the brake controller itself on different vehicles. 00:52

We know where we are going to put our brackets so lets make some marks on the dashboard and install the bracket. Before we drill we can reach up in there and make sure there is nothing in the way. It looks like there are two layers of plastic so I think we will be okay in between. Now install the set screws into the brake controller. Next we can take up the cord and wrap it up with a zip tie. We have got everything mounted up and you can tell right away that our brake controller has the two lights on and that means that it is giving power to the brake controller and we are good to go. Lets go out back and start changing out the 4-pole to a 7-pole connector. 01:52

At the back of the truck underneath and we removed the spare tire and we are going to look at the driver side frame rail. You are going to see the connection point right here and we will push down this tab right here, there is a little lock. You should be able to pull it apart. Sometimes this little red divider gets pulled out with it but it just pushes right back into position. We are going to take our harness to our 7-pole connector and we are going to run it through the last brace here on the frame and just follow it back through the wiring and pull it out and we are going to snap the two halves together. Take the other half and plug it in here. Look at this ground screw right here. Take that apart and attach our ring terminal for the ground. The next thing we are going to do is mount the 7-pole. We are going to use a couple of separate part numbers for that. We are going to use PK12711U which is our OEM hardware bracket and we are also going to use PK11926 hardware kit for the bracket. Take the mounting bracket and we are going to attach it directly to the bottom of the bumper. We will run the wire harness through and connect it to the 7-pole itself. Push it together and push that white lock into place and you will bolt that to the bracket. 03:36

Now we are done with the back half of the vehicle, now we need to get underneath the hood of the vehicle and add a couple of fuses and relays. We are underneath the hood and we need to get to the power distribution box, remove the lid. There is a variety of fuses and relays that come with the kit. On this part here you will have to go to your owners manual in your vehicle and it will tell you where the tow package fusees and relays go. In this case we are only giving power to our brake controller so we do not have to worry about that circuit. However we do not have 12 volt power going out back so we need to install a fuse for that. That is going to be this square fuse and it is going to get installed in this socket right here. Now we can go out back and test the connector for all of the functions. We have got our truck hooked up to our load or it could be a trailer, and we will use our manual override so we have got numbers so we have got a good solid connection and also the C tells us we are connected. The small knob up here is our gain which controls how much voltage goes out to the brakes on the trailer. All the way forward is basically full blast and all the way back is basically off. Somewhere in between you will find a setting for your trailer. There you have it for part number 90885-3035P and part number 118242.

The wiring harness was easy to install. Several fuses and relays are included, but the instructions are generic to cover a wide range of trucks. Depending on the year and options on your specific truck you may use all or only a few of the fuses and relays. This was confusing and I hope I got the correct pieces in the correct locations.14837
