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.

Excellent product. High quality and easy installation. Made better than a factory harness I have on a different vehicle. I also purchased the mounting bracket and hardware kit. The bracket is wonderful and most of the hardware was good too. The self tapping screws both got the heads broke off, but it was my fault, not the screws. 85108


Still working flawlessly, the factory 4 flat isnt working but this one still works like it did when brand new. Highly recommended.

Installation was a piece of cake. Everything worked exactly like the video explained and everything was in the box to complete the job. The lady on the phone even reminded me to add a bracket. Like everyone else, I tried locally to get these parts. The local guys (Oreilly, Napa, Autozone & even the custom accessory shop) told me this harness did not exist. I've installed several of these style harnesses on different vehicles. This is my first from etrailer and was by far the most complete kit ever. Everything fit perfectly. Instructions and video were exactly correct. Zero regrets. Worth the money. Wish I would have known about etrailer sooner. Big thanks to the local guys for forcing me to shop online. 100769

We purchased a 5th trailer and needed to have my Ford F-150 wired for trailer brakes and 7 pin harness. Checked your website and was able to find all parts I needed. The installaton videos you have are awesome, they help out so much. Ordered all parts and they arrived quickly. All parts were identical to what was ordered. Had everything installed and wired in, in about 45 minutes. They wiring harness was perfect fit and they trailer brake control harness also exact fit. My overall experience was awesome from placing the order and the e-mails to let me know who took my order and who sent it and tracking it. I will recomond etrailer to everyone I can. Thanks to etrailer we are ready to tow our trailer.****** 34253

The product works as described. The only problem I encountered was on a 2001 F150 crewcab. The connector that connected to the wire harness coming from the front of the vehicle did not have any catch mechanism so it wouldn't stay together enough for the right side lights(on truck and trailer) to work. I used some channel locks and pushed together as far as I could without breaking anything then used electrical tape to tape it together. Of course after I crawled out form under truck and put spare back in place I realized I should have used a zip tie to hold it. Would probably last longer and hold better. Everything works well. I do not have a brake controller hooked up on vehicle yet. 113986

Installation of the actual harness was easy. However, if you have the factory 4-pin flat connector without the 7-blade connector, you will need to purchase or make a bracket for the 7-blade connector. On an F-150 there is very little space to add an additional bracket, so I extended the 4-pin bracket and made the extension so that it held both the 4-pin and 7-blade connectors. There is a bracket, a Ford part, specifically marketed for the Harley Davidson edition, FY3Z-14A163-CA, which may or may not fit the standard F-150. Also, another part, FL3Z-14A163-BA may or may not fit. 138797

7-way harness has a weak locking tab on back of connector which locks it into the back of the socket. It promptly broke while handling connector and socket prior to assembly on vehicle. The 30-amp fuses included were of the wrong type for a 1999 F150. The fuses are a blade type maxi-fuse, and the 99 F150 uses a square type of fuse. Luckily, both fuses were already installed in the vehicle. The relays fit perfectly. 83591

This was great, I bought it for my 2000 ford f150. It was easy to install. Only trouble I had was securing the ground to the frame as my ground bolt was corroded with rust (live in Minnesota) such that I couldn't loosen it and had to drill a new hole for the ground. Another note I bought the mounting hardware as well, and it was the wrong mount so be careful and make sure you get the right one if you order the kit 108425

Great purchase all around. Paid a pro (?) to install electric brakes but he didn't do it right. I ordered the harness myself and installed myself then took it back to the pro (?) to have him test it and now is he embarrassed.

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

Very easy to install thanks to Ford. Very disappointing that it did not come with the $4.00 mounting bracket for the back of my truck. Had I been told this during the order process I certainly would have bought it. Its bundled with enough relays/fuses that it should've been bundled with the bracket. Thats the only complaint. 82299

To install a 7-way on your 1999 Ford F-150, you will need Ford Replacement OEM Tow Package Wiring Harness, part # 118242, which includes all necessary adapters and fuses. Before installing part # 118242, you will want to disconnect...

  • Replacement 7-Way Trailer Connector and 7 and 4-Way Plug for a 2003 Ford F-150 Super Crew
  • If your 2003 Ford F-150 has the 7-Way and 4-Way and they are separate (not mounted in the same plug like # HM48470 for example), the 4-Way will still be functional as the Ford Replacement OEM Tow Package Wiring Harness, # 118242, just replaces the 7-Way connector and wiring, and includes the fuses and relays if needed. I have included a link to the installation details and a video that, in part, shows the harness being installed for reference. If you need to replace the 7-Way wiring...

  • Troubleshooting Running Lights on Trailer Not Working When Connected to a 2001 Ford F-150
  • If your 2001 Ford F-150 is equipped with a factory 4-Way trailer connector, the Tow Ready Custom Fit Vehicle Wiring, # 118242, should work. There are a couple of things you can check. First, there are a few fuses that need to be installed if you have not done so. I have included a link to the instructions below. The first few steps address the fuses. Also, you can check to see if any fuses are blown. A tow package running light fuse might be blown and need to be replaced. Also, check...

  • Troubleshooting Replacement OEM Tow Package Wiring Harness # 118242 on a 2000 Ford F-150
  • The best way to determine where the issue is occurring would be to test the 7 pole plug with a circuit tester, without the trailer connected. Have a friend sitting in the cab press the brake pedal and engage each of the turn signals while you test the corresponding prongs on the plug. If you are correctly receiving power at the 7 pole plug, you will need to turn your attention to the trailer. If not, I would check the connection point between the # 118242 harness and your vehicle,...

  • Brake Controller Wiring on a 2003 Ford F-150
  • To install your brake controller, you will need a Brake Control Wiring Adapter, part # 20260. Plug one end into the connector under the dash, and the other end of the adapter would wire up color for color to your brake controller. To upgrade your 4-way connector, use the Ford Replacement OEM 7-Way Wiring Harness, part # 118242. Both parts are very easy to install with no cutting or splicing required.

  • Locating Brake Controller Port on 2000 Ford F-150 To Install Hopkins Brake Controller # HM47294
  • The factory brake controller plug should be located under the dash to the right of the steering column. It should be located towards the center of the dash and may be tucked up and out of the way behind some wiring. I have linked an FAQ Article that shows the location of the plug. You will need the Ford Adapter, part # HM47715, to plug into the brake controller harness and the Ford plug under the dash. If you have a factory 7-Way on your 2000 Ford F-150, installation is complete after...

  • Finding Fuse and Relay Locations for Tow Package Wiring on a 2005 Ford F-150
  • If you look at the owners manual for the truck and/or the legend on the power distribution box lid it will tell you the locations of the fuses/relays that are related to the tow package wiring. I found an online version of the owners manual and the fuse/relay section starts on page 224. For fuses it looks like the trailer tow parking lamp fuse is in location 10 and the relay is location R201.

  • How To Install A 7-Way Connector In The Bed Of A 2002 Ford F-250 For A Fifth Wheel
  • If you have a factory tow package with a factory 7-way trailer connector already on your 2002 Ford F-250 Super Duty, then I have a couple of recommendations to put a 7-way in the bed of your truck. The Draw-Tite Wiring Harness, # 51-97-410, will plug inline between the OEM wiring harness and the factory installed 7-way connector under your truck bed. You will retain the use of the factory 7-way on the bumper and then have 9 feet of wiring harness to have a 7-way in your truck bed. The...

  • How to Install A 7-Way Connector On A 2010 Ford F-150 With A 4-Way Flat Connector
  • To convert the 4-Way flat trailer connector on the back of your 2010 Ford F-150, I would recommend using a 4 to 7-Way adapter, like our part # 37185. You will plug the factory 4-Way into the back of the adapter and hardwire the remaining 4 wires. The white wire gets grounded to the vehicle frame. The blue wire gets connected to the electric brake controller output (blue wire on a brake controller). The black wire connects to the positive battery terminal with 10 gauge wire like # 10-1-1,...

  • Compatibility of Ford Replacement OEM Tow Package Wiring Harness # 118242 with 1996 Ford F150
  • I spoke with my contact at Tow Ready, who tells me that the # 118242 will not work for the 1996 F150. The 1996 model does not have the connector for the 118242 to plug into. If your F150 does not already have a 4-pole trailer connector on it, you would need the T-1 connector, part # 118316 and the 4-Pole to 7-way adapter, # 37185. Since the 1996 F150 should have the connector under the dash for connecting a brake controller using the # 3035-P harness. At the end of the drivers side frame...

  • Troubleshooting a Replacement Ford Tow Package Wiring Harness for No Left Turn Signal
  • I would try unplugging the harnesses and relays and then plugging them back in as it sounds like the left turn signal circuit is not making contact somewhere and it could be as simple as reconnecting the harness to fix the problem. Next. I would check the vehicle side plug that the Tow Ready Custom Fit Vehicle Wiring # # 118242, plugs into. If this circuit is functioning properly then check the wires coming out of the new connector to determine if the power is getting to the 7-Way harness....

  • Parts Needed to Add a 7-Way Trailer Connector to a 2007 Ford F-150 with Factory 4-Way
  • To install a 7-Way trailer connector on a 2007 Ford F-150 with a factory 4-Way, you will need to use # 37185. This is part plug and play and part hardwire, but the hardwire locations are easy to access. You will need to ground the white wire to the vehicle frame. The purple wire is for reverse lights if needed. You would need to tap into a reverse light wire on the vehicle. The blue wire is for the trailer brakes and the black wire is for 12 volt power. To connect these wires, follow...

  • Will 4 to 7-Way Adapter # 30717 Plug In Directly On a 2001 Ford F-150
  • Part # 30717 is meant to adapt a 4-Way plug to a 7-Way plug. In order to use the adapter, you would need to have a basic 4-Way plug like part # 118344, and the adapter would plug into the 4-Way connector. You would then connect the additional wires on the adapter to power the rest of the prongs on the 7-Way plug. If you are wanting to move your current 7-Way connector from the 2005 Excursion to the 2001 F-150, I cannot guarantee that it would be a direct fit. We do, however, offer...

  • Tow Package Fuse and Relay Locations for 12 Volt Power on a 2006 Ford F-150
  • According to an owners manual I found from Ford for the 2006 F-150 the 12 power fuse for the 7-Way is located in spot 106 and requires a 30 amp cartridge fuse. There is also a Full ISO relay needed in spot R05. Your owners manual has a section on fuses and relays for more information. The fuse you should be able to get at an auto parts store but the relay is most likely a dealer item. I would first test the 7-Way trailer connector to see if it has 12 volt power on the pin in the 1:00...

  • Powering Reverse Lights on Pop-Up Camper with 6-Way Trailer Connector
  • The idea you propose, using a switch to power your reverse lights using the 12-volt accessory circuit off of your 6-way trailer connector would most likely work. I would first recommend you find out where that 12-volt circuit terminates on the trailer. Some pop-up campers have a battery for interior lights. The 12-volt accessory circuit keeps that battery maintained. Had you not already purchased the OEM 6-way replacement connector, I would have recommended going with the 7-way replacement,...
