Video Transcript for Tow Ready Tow Package Wiring Harness Installation - 2002 Ford F-150

Today, our 2002 Ford F150 SuperCrew Cab, we're going to install part number 118242. This is a Ford replacement OEM tow-package wiring harness. Now, what this will do, it will upgrade your preexisting 4-pole harness on tow package up to a 7-pole. Now, our new upgrade harness will actually work with a factory 4-pole wire harness. In this case we don't have our 4-pole anymore, so that's why we're upgrade. Our connection point is right here on the frame rail on the driver's side.

Yes, you definitely want to take the spare tire out of the way so you can see what's going on. This is our connection point and this is our ground. We're going to have to take apart the ground and our connection point. Then we'll go ahead and move this off the frame rail. A small pry bar or trim panel tool will work to get the classic part off here; we'll have easier access to our wire harness. Now, we need to take this apart, push down on this tab, and pull it apart.

Then we can go ahead and start to install our new parts. We've got our new wire harness and basically T into the middle of these two connectors; push them together until they click. Then, we'll go ahead and install our white wire at the ring terminal with the original one and original screw back into the frame. We'll snap this back into its original place, a little push fastener. I'm going to take the indirect cable; it'll go towards our bumper. I like to route it over the frame, back down to the bumper.

Now, at this point it's personal preference how you route your wire harness to the eventual location of your 7-pole connector. Let's go ahead and use a zip tie to help contain our wires, keep them safe and secure. Now, the kit doesn't come with many zip ties, so you may want to go get yourself some. Now, this is our 7-pole connector that'll eventually plug into the back of our wire harness here. This is like Ford factory.

To do that, I will now mount a couple of brackets to hold our 7-pole in place. Now, the bracket we're going to install is part number 18140 from Tow Ready. This is their universal mounting bracket. This bracket is going to attach to the bottom of our hitch and use this clamp to hold it in place. Now you take the screw and a clamp and bend it out of the way to make it easier to run the clamp through and then push it back up. Then use a 5/16ths nut driver to tighten it up. I'm just going to bend that guy up and out of the way for the excess. Now, the bracket we're going to use to hold our 7-pole connector up will be part number PK12711U. This is a mounting bracket for 7-pole connectors from Pollak. Also, we're going to need some hardware to do this. This will be hardware installation kit PK11926. Now to make our connection we're going to use the parts that came with our first bracket to attach these two. Our hardware kit will work with the 7-pole connector itself. A number two Phillips screwdriver will work to tighten down our hardware. Let's go ahead and mount our 7-pole connector, using the hardware kit for 7-pole bracket; flat blade screwdriver for these screws. Then, we can go ahead and plug our wire harness into our 7-pole connector. Now on this connector here, it's a good idea to use some dielectric grease. We'll be using part number 11755 from Lubrimatic. Push these two together until they click and there's also a small grey lock that goes on the end here. Now, typically this piece is already installed on here, but you might want to take it off before you do your installation to make it easier to snap together. So, to take it off, you just push down right here with a really small screwdriver. Push down in the middle and then remove it. When we need to use it, we just line it up and push it into place. All right, next we'll get underneath the hood of the truck and we'll go to the fuse panel here. We'll open it up, take the lid off. There's a couple of relays and fuses that we have to install. At this point, you definitely want to go by the owner's manual and find the locations for your fuses. Now, a lot of times the relays and fuses are already installed onto your truck. So, it's just basically you got to just investigate and see what you need and what you don't need. Now, in our particular truck, we only had to install the backup relay, which is located right here. On our battery charge circuit for our trailer, the relay goes right there. Everything else is already installed on the truck. The fuses that came with the kit, we couldn't use in this one because they're already fuses in the areas of the fuse box of our truck. So, we are done. We have everything in place it's a good idea to test it out with a tester before you try it on a trailer. With that, that'll finish it for our install, part number 118242 full replacement OEM tow-package wiring harness on our 2002 Ford F150 SuperCrew Cab. .

I have a 2003 f150. Recently bought a camp trailer and needed trailer brakes hooked up and 12 volt to charge the trailer battery. My truck had a brake controller already installed and very poor hack job for the trailer brake wire into the existing harness.This plug in harness cleaned it all up and Now have trailer brakes and 12 volt to the trailer. One thing to check for is the relay for the 12 volt, my truck already had one in place but was not working , changed it out for the one supplied and now works. 700098

My F150 had an OEM 4 pin trailer plug and hitch. The 118242 - 7 pin connector with wiring harness is the ticket. The hardest part of the install was dropping the spare tire. The plugs connect directly to the factory plugs and the harness length is the correct length. The 3035-P brake controller connector harness was just as easy. Plugs right in to the OEM plug next to the ECM connector and the other end into the brake controller. The PK12711U-26 - 7 pin bracket and hardware kit fastens directly the OEM bracket that is on the hitch. My truck had an OEM 4 pin trailer towing set up with the hitch. The OEM hitch had the bracket welded on it to attach the 7 pin mounting bracket to it. These kits make this install very easy and professional looking. If I have one complaint, the hardware kit to attach the 7 pin connector bracket is set up to fasten the bracket directly to the bumper with 2 - self tapping screws provided in the kit. The kit also includes 4 #12 machine screws with toothed washer nuts to attached the 7 pin connector to the bracket. This is fine if your truck hitch doesn't have an attaching bracket welded to it. The kit should included in it 6 #12 machine screws and nuts along with the 2 self tapping screws. Since my OEM hitch actually had a bracket welded to it to attach the 7 pin bracket to it, I had to use two other #12 screws and nuts to attach the 7 pin bracket to the OEM bracket on the hitch. Not a big deal, just a thought. It took me about 2 hours, start to finish to install the 7 pin connector, trailer controller, and add the two relays in the OEM relay/fuse box under the hood. I highly recommend these kits. 322339

I do not like to leave bad reviews, however I was initially impressed from what I heard about family members who have used etrailer. I purchased the above product for a 97 ford f150 with factory tow package. This product was confirmed to fit this truck, and was listed as specifically for this truck. However the connectors are not even close, which I can understand considering that the truck was built in mid 96 as a 97 model. I called into customer service after doing a great deal of research, and discovered through ford that there were different variations of electric brake configurations for this year. I needed to return said product, that I purchased based on the websites EXACT description and etrailer wants to charge me almost 12 bucks to return a product that they advertise as "confirmed fit". I would have no problem paying for shipping if this was MY error. Customer service stated that they would request to waive shipping, confirmed my phone number, stated they would call back....never did. One would think you guys would do your homework on this before advertising a product in such a manner. I was easily able to find out that depending on when and where my truck was built would determine what type of harness is needed. 451374

The wiring harness worked great. There are instructions and a video that made it simple. I knew exactly what to do before I started. We needed this in order to pull a larger trailer that has electric brakes and didn't want to cut and splice wires. The connectors plugged right in to the OEM connectors. I only wish I would have thought of it sooner so I didn't have to pay for the next day delivery...but on the other hand Amazon was like a 2 week delivery and Ford was triple the price. I was happy that someone offered next day delivery. 318910

this adapter is not the only item i bought, i ended buying multiple plug adapters in hopes of finding one that worked, well to make a long story short i ended up taking my motorhome with all the plugs that i had bought to giant r.v. and sales that said please fix it. the bill came to 679.01 so instead of being a plug and play it turn out to be plug and pay. but on the bright side i have extra plug that i will never use. 490003


Comments

Thanks for the follow up Charles, This 7-way is intended to be a 7-way replacement for the trailer connector on older model Ford F-150s but is is not a fit for either your 2017 F-150 or intended to be used as a flat tow wiring harness for flat towing your F-150 behind your motorhome. I have included a link to the trailer connectors confirmed as a fit for your and a link for the vehicle tow bar wiring for flat towing your F-150 behind your motorhome.

The 7 pin wiring adapter for my 2004 F-150 Heritage worked great. My truck did not come with the towing package so it only had a 4 pin trailer connector. My new travel trailer is a seven pin with trailer brakes. The instructions and on line video made the install a breeze. I really liked it because it was “plug and play”. It only took me about 15 minutes to install. Thank you etrailer!!! 695157

After much research, I decided to buy what I needed for my trailer brakes on my 99 F150 from etrailer.com. I'm very glad I did. The wiring harness plugged in just as they said it would. The brake controller was a breeze to install. Shipping was fast and free since I spent over $99.00. Over all, I am very pleased with what I got, shipping and the followup on my order. I will recommend etrailer.com every chance I get. 509013

The whole process from ordering to installation was simple. Only thing that coulda been an issue, the two 30amp fuses that came with kit were flat type fuses. My 02 Ford F150 takes square fuses. It didn’t matter though since there were already fuses installed!! Works like a champion!! 486488

Seems to be a quality part. Arrived ahead of time and was priced good. But it does not match up with my 99 Ford F-150 stepside. There is no pig tail for the rear lights and now I have no brakes blinkers or anything. Well that was the reason for buying this because the original harness was destroyed. Is there a different harness I should have gotten? 438750

  • Circuit Configuration in RV-Type 7-Way Trailer Wiring

The photo I linked shows an actual trailer plug # A10-7W6 like yours and the circuit arrangement is the same as your photo diagram. For reference, the included article covers all wiring formats in detail. The item you referenced, replacement OEM wiring harness # 118242, is configured in the same way.

  • Solution for Needing 13A576 For 2006 Ford F-150

I have linked videos on both parts for you. The Ford part is twice as much and you might still have to purchase from them the relays and fuses that are already included with # 118242.

If the 4-Way connector is a factory connector, the wiring harness will be connected to the vehicle wiring harness along the driver's side frame, between the back tires and the end of the truck bed. I have attached a photo showing what the connector will look like. If you find this connector on your truck, you can use...

  • Adding 7-Way and Brake Controller on a 2001 Ford F-150 with Factory 4-Way Trailer Connector
  • If your 2001 Ford F-150 has the factory 4-Way flat trailer connector then you can use harness # 118242 to add a 7-Way. Once plugged in in place of the 4-Way harness and after the included relays and fuses are installed then it will be fully functional including the orange and blue wires. You would only have to splice into them if you were hardwiring in a 7-Way. But for your truck and year you can just plug in this harness. The orange wire will be active and the blue wire will be ready...

  • 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...

  • Does the Ford Replacement OEM Tow Package Wiring Harness Include a Battery Isolator
  • The Ford Replacement OEM Tow Package Wiring Harness, # 118242, includes the wiring and relays needed to replace the factory 7-Way on a truck that has the factory tow package. If the original tow package included a battery isolator feature it would be part of the tow package wiring on the truck and not in these replacement items. In order to see if the 7-Way has power even with the key off, you can test the 7-Way at the back of the truck with the key off using a circuit tester like #...

  • Recommend 7-Way Wiring Harness Needed For 1999 Forf F-150 With No Trailer Connector At All
  • I believe the connector you found is the connector you will use to plug in the wiring for your 7-way connector. There should be a wiring connector along the drivers side frame rail at rear of truck between the rear wheel and the rear of truck (see FAQ and video). 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...

  • No Power Inside Travel Trailer When 7-Way is Connected to 2006 Ford F-150 Super Crew
  • It sounds like you are not getting 12 volt battery power to the 7-way connector at the rear of your 2006 Ford F-150 Super Crew. If you look at your 7-Way vehicle connector on your truck, the pin at the one oclock position is for the 12 volt battery power. I am including a picture of a 7-Way vehicle connector that will show the pins and their functions. You will want to test that pin at the one oclock position with a circuit tester like the Quickee Tester, part # 40376, to see if you...

  • Adding a Brake Controller to a 2011 Ford F-150
  • If your 2011 Ford F-150 came with a factory installed 7-Way trailer connector or even a factory 4-Way trailer connector then you can plug in a brake controller using the proper wiring harness. For a controller I recommend the P2 # 90885 because it's easy to set up and use and it is reliable. The wiring harness needed to plug this controller into your truck is # 22292. I have linked a video showing how and where this harness plugs into on your truck. If your truck came with just a...

  • Installing a 7-Way Trailer Connector on a 2001 Ford F-150
  • Your 2001 Ford F-150 likely came with a factory 4-Way and someone spliced in a 7-Way at some point. To determine if the truck is set up already for a fully functional 7-Way you can check under the hood to see if the necessary relays and fuses are present. If they are then you could use Curt harness # C55242 and it will work. If the fuses and relays are not present then they would also need to be added and I recommend harness # 118242 which includes them as well as the 7-Way. I have linked...

  • Replacement 7-Way Wiring Harness for 2005 Ford F-150 with Factory Tow Package
  • From your question it sounds to me like someone has cut off the tow package plug on your 2005 Ford F-150 and wired in a 4-way connector. In this case you could use the Hopkins Adapter 4-Pole to 7-Pole and 4-Pole, # 37185 which will give you a 4-way and 7-way connector.

  • No Power on Brake Controller Blue Wire on 2002 Ford F-150
  • It wouldn't be a fuse since the brake controller is getting power. If the truck is parked then there may not be any power on the blue wire when stepping on the brake pedal (depending on which controller you are using) but there should be power when using the manual override. There are some things you can do to test a brake controller. In the truck cab you will need to sever the blue wire several inches from the back of the controller. Then use a circuit tester such as # 40376 to test...

  • 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,...

  • 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 Electric Trailer Brakes and Running Lights not Working on Trailer, 2006 Ford F-150
  • I have a couple of ideas that may help solve the problem you are having on the 2006 Ford F-150. First, you mentioned that the truck has the tow package. It is possible that you will need to add or replace fuses and/or relays to allow the tow package to be fully functional. Your vehicle owners manual should have the locations of these fuses/relays and you can check to make sure everything is present and in working order. Next, you can check some of the wiring to determine if it is the...

  • Turn Signal Lights Freeze when Trailer Is Connected to a 2010 Ford F-150
  • It sounds like there is either a short circuit causing constant power draw or back feeding or the truck connector and trailer connector are wired differently and the turn signal issue is a result. To determine where the problem is you can plug in a different trailer and if the same issue happens then there must be an issue with the truck tow package wiring. If it does not happen then the issue is on the trailer. You can test the truck connector with a circuit tester # 40376. Have...

  • 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....

  • How to Determine the Factory Trailer Wire Functions on a 2005 Ford F-150
  • I may have some information that will help, however, vehicle manufacturers are notorious for changing the wire colors on their factory trailer wiring, so the best way to determine the function of each wire is by testing. To test the wires, I recommend using a circuit tester like part # 40376. Find a good ground for the tester and test each wire as a helper activates each light function on the truck. We had a 2006 Ford F-150 on our lot with the factory tow package wiring, so I went to...

  • PowerTrac Trailer Brake Controller Not Lighting Up Installed on a 2001 Ford F-150
  • On the PowerTrac brake controller # 39523 when no trailer is connected the light on the controller will either be flashing or off. It isn't until a trailer is connected or the brake controller is operated that the light will come on. Did you hardwire in the brake controller or did you use the pigtail # 3035-P to plug it in? If you hardwired it in then it is possible that the red wire on the controller is not connected to the correct brake switch wire on the vehicle. There can be more...

  • Installation of Brake Controller On My 2011 Ford F-150 Without Tow Package
  • It is possible that the wires you are looking for have been terminated farther up the frame rail or may not have been ran back. Typically the wires would run to where the factory 4-way is plugged into, usually near the spare tire. If you cannot locate the wires, you will just need to hardwire the brake controller and 7-way, which is not as bad as it sounds (we have a kit for this). You will need the Brake Controller 4 and 7-way Installation Kit, part # ETBC7. To install, you will begin...

  • Recommendation for Replacement 7-pole Factory Wiring Harness for 2001 Ford F150 SuperCrew
  • The Tow Ready wiring harness you referred to, part # 118242 can indeed be used to replace a damaged harness on a vehicle with an existing 7-way. A replacement 7-way as well as spare fuses and relays for activating the tow package are included. If you do any kind of hard work with your truck at all, these spare parts will most likely come in handy.
