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. .

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
by: Duane G.06/04/2014
nice plug and play installation, video on your web site helped to speed the process as well as clarified that this was the right part that I needed, very good quality although the maxi fuses were not correct for my application but mine already had the fuses in place. 134345
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
Plug and play on my 2003 Ford F-150. Works great. I found the installation video on the website especially helpful. Great job etrailer.com!! 131483

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
Your product fits perfectly I customize the 7 way plug into my bumper I didn't like the way the bracket let hang down so far ill send another picture with me pulling my drag truck with the van thanks again. 106753
by: jr fults01/20/2014
if this was any easier to install i think i could have did it blind but everthing went in place very easy no problem if you take your time it might take 1 hour that saying you have the tools on hand that you will need their video are very helpful if you find you are having a problem but i think evening a cave man could install this great products.happy happy happy 114296
by: Bill McC05/14/2013
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. With the video online I should have done it myself from the beginning. Thanks ill be back when I need something else 80127
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
by: Al G.07/08/2012
I ordered the prodigy 2 controller, the wiring harness, hardware kit and mounting bracket. quick shipping and instalation was super easy with the how to video. I installed the whole kit in under an hour and towed 1650mi right off. Just as described and the kit worked flawless! literally plug and play. I can't say enough good about it. 47149
by: Nick L05/29/2013
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
by: John Malkin - Denver04/04/2014
By far the easiest and best plug and play product we ever purchased. Have a 2003 Ford 150 and a 2011. Installed these along with Tekonsha P3 Conteollers and it literally took 1 hour to install and be on the road. Great product - great price. WATCH THE VIDEOS -- dead on accurate and helpful John Malkin - Denver 123758

Easiest trailer plug I have ever installed...lowered spare tire (but did not remove) and then unplugged the stock wire plugged this in line and mounted it all to the brackets i purchased here at same time, had it all wrapped up and completed in under half hour, with my 4 year old daughters help of course! 187455
by: John Malkin - Denver04/03/2014
To be honest -- the hardest part was finding the key for my spare !!!! Found it though and within 20 minutes I was in parking lot checking the brakes. Takonsha P3 coupled with eTrailers wiring harness and accessory make this a great DIY project. Don't forget to purchase a mounting plate !! 123583
by: Dan S04/05/2012
Worked great. Ordered it on Tuesday, got it on Friday. It was the perfect length for my 2000 F-150 and all the connections, fuses, and relays fit perfect. I like that the instructions and video were posted on your website so I knew exactly how to install it before I even ordered it. 36240
by: Greg p.05/25/2012
great products, easy instructions, was told by several camper stores that this product was not available and i would have to "hard-wire my truck to accept a 7-way plug, but etrailer had exactly what i needed and at a great price! i will continue to shop with etrailer from now on! 41643

by: Frank M09/20/2011
Product was as described. Easy to hook up. The only thing that is not clear is that it does not come with the L bracket to mount it to the truck. I went to our local store and their L bracket will not work with this plug, so don't forget to order the bracket as well. 24280
by: Joe W07/19/2009
quick shipping, easy install this sysytem couldnt be simpler, unplug a connector, pug the adapter into the two ends and run the bolt through the ring termional and tighten back in place. a basic mounting bracket for the recepicle would have been handy however. 2142
by: R Rrebbs03/16/2011
The install could not have been easier, unless you had some one else do it. Fast shipping and the E trailer customer service is great. The only problem I had was I forgot to order the mounting bracket mount bolt/screws. The video was made install easy. 9442
Fit like a charm...Watch the video...it simplifies the installation...and it gives you a heads up on the little red factory connector ring that doesn't necessarily want to stay where it belongs...mine moved but it was no big deal knowing ahead of time. 149561
Fits great and no fuss plugs. Added a little Dielectric grease for good measure and have had no issues. well worth the extra money over a "Universal" mount. all the wires had been well terminated and low resistance. Clean install clean look. 8000
by: Kyle H.05/25/2013
The wiring harness was very easy to install. However, the kit didn't come with a bracket to attach to the bumper. The instructions were just enough information to be helpful, but not too excessive. The package also arrived in a timely manner. 81925
The installation of this product was very easy. It was helpful to review the video that was on line for the product. Once the installation was complete the product worked flawlessly. It only took me about 30 min to install and it looks clean. 160405
by: Hank H01/02/2011
Great Service I have ordered several times from E-Trailer and have always recived what I ordered and more importain what fits. Last order they up graded the shipping time on there own, not needed but very nice just the same. HH 4888
by: Phil S09/16/2014
This product fit perfectly and solved all my trailer wiring issues and some from the previous owner judging by the cuts and splices. The wiring now looks like it should. I would highly recommend E-Trailer products. 151223
Really easy to use both of these products. Only problem is making sure you have the key to lower the spare tire to get to the connection for the 7-way. Shouldn't take over one hour to do both installs. Works great. 40852
by: Al C.10/29/2012
I was extremely pleased to get my wiring harness ahead of the predicted schedule. The wiring harness directions were exact and percise. I was able to complete the job of installing the harness in about 10 Minutes. 58310

by: Christopher W.05/05/2012
Great products with no splicing of wires. I did it myself, just plug it in and you are ready to go. I am so glad I ordered the mounting bracket. I just wish it had the screws included with the mounting bracket. 39504
by: Sam Z.08/15/2014
Remove the spare. Disconnect the old wiring. Install the new wiring. Secure with some ties and presto! Done. The only way it could have been any easier is if I had someone else do it! Thanks etrailer.com! 146878
by: Shawn Guffey04/08/2012
The product was exactly as advertised. Very easy to place my order online. Order was promptly processed and item was shipped very promptly also. Very pleased with my first transaction with etrailer.com. 36558
I was impressed with entire process of ordering and receiving this wiring harness. I installed it myself after watching the video on entrailer on how to install it. It led me through every step. Thanks! 18746
Awesome, installed relays, dropped the spare tire, plugged in, zip tied,connected ground, tested and was perfect, new boat in tow! would have been nice if there was hardware with the mounting tab. 187221

Part was recieved as and when expected and was exactly what I was expecting. Appears to be working as expected and now it is a matter of how it continues to function for the next couple of years. 10520
