Today we're going to be taking a look at the Ford Replacement OEM Tow Package Wiring Harness with a seven way connector. This product fits numerous vehicles, so to make sure it works with your particular year and model, you can use the vehicle fit guide located on our website at etrailer.com. This is an exact replacement for your damaged OEM wiring harness. It's going to install quickly and easily, and it upgrades vehicles from a four flat OEM wiring to a seven way connector. The existing four way flat harness on your vehicle will still be functional. The unit's designed to connect directly to the standard OEM connector, you can see right here everything that it comes with. Your going to get the actual harness, your going to get your new seven way connector, plugs into this port right here on the harness.
Your going to get a hardware kit that's going to include two zip ties, detailed instructions, and your going to get the necessary fuses and relays. The connector right here, to make sure this is easily accessible at the back of your vehicle, we recommend using a mounting bracket. This is going to fit mounting bracket PK-12711U. That item is sold separate if your wanting to add a bracket to the vehicle for your seven way connector. You can find it here at etrailer.com. Now when it comes to installing the unit, you'll need to disconnect the vehicles negative battery cable, install the included fuses and relays according to the detailed instructions, locate the vehicles wiring plug that's going to be located in the rear underneath the vehicle, inside the driver's side frame rail.
Separate the plugs on the vehicle, and then install the trailer tow harness between mating plugs. These connectors are going to match up perfectly, they're going to snap lock together for a nice tight secure fit. Once you have those connected, make your ground connection, that's going to be you white wire with the inaudible 00:01:37 attached to it. That's going to get connected by using the existing ground stud on your frame rail, and then plug the seven way socket into the harness on this side. Push it in until it snaps together. It's got the locking tabs on it as well for a secure fit.
Once you have that done, you can reconnect the battery cables, test your installation, you can secure all your loose wires with the included zip ties or cable ties. Then you can mount the tow harness in an accessible location using the mounting bracket like I mentioned earlier. Please keep in mind, the unit can only be used with a factory four pole harness. This will not work with the factory seven pole harness. The instructions are detailed, they include some images in there to help with the installation process. A couple more things that I want to mention before we wrap up the video, here on the seven way connector, you can see it has a nice spring loaded lid, has a little tab right there so you can easily get that open, and get everything connected as you need to.
Really nice design. I just want you to know that your wiring is going to be protected. It's got the nice wire loom that goes around there to protect the wires. Again, when installing this, I do recommend going ahead and using the zip ties, to secure the wires up and out of the way, and keeping them safe. Especially during travel, and when a lot of grim builds up under the vehicle, having them tucked up and out of the way. Maybe even along the existing wiring harness is really going to help extend the life of this wiring harness, and just the wires. That wiring loom is going to help as well. That's going to do it for today's look at the Ford Replacement OEM Tow Package Wiring Harness with a seven way connector.
Average Customer Rating: 4.8 out of 5 stars (151 Customer Reviews)
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

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

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
by: Rick W.07/02/2014
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

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

I needed a 7 pin wiring system and a friend told me about etrailer.com. I looked at all the options listed for brake controllers and didn't know which to choose from, I called tech support and explained what I wanted and they reccomends a controller for me. I also wanted plug and play, no cutting/skinning/splicing wires for me, I wanted it simple. Well I got simple, very easy install and everything works perfect. Very satisfied and I will be buying more products in the near future. 325943

Very easy to order. Came on time and was exactly as it said it would be. Very simple to hook up and in minutes my problems were solved! Previous plug that was on my truck was installed incorrectly by previous owner. I hooked up a brake controller for my pull behind camper and could not get power to the controller. After installing the correct plug and harness that I ordered from your site the problem was fixed literally in less than 1 hour. Thanks for making it very simple! 271591

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
by: Mike F.09/22/2016
If you did not see my review for the bracket then I will recap. I did not use the bracket except for a template. Mounted the plug in the factory bumper just left of the license plate recess by knocking it out with an electrical knockout cutter. Drilled the mounting holes and installed the wiring harness. Great product and great video, I highly recommend etrailer.com. Package properly, came early, fit was perfect. 297816

I put off wiring my truck with a 7 way plug for years because I didn't want to deal with the hassle...WRONG. I found this somewhat accidentally and installation was easy. One word of caution; read the short instructions twice so you don't get worried if you have extra parts. My installation did not require the two blade fuses (but of course that was clearly stated in the instructions). I am very pleased. 246130
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: Chris M09/13/2016
Simple install! Took longer to get the spare tire off then the installation of the harness did. Make sure to purchase the mounting bracket (sold separately). I also bought the no drill mounting bracket, but chose to use self tapping screws and went straight into the bumper. Makes it easier to hook up, and it's solid. Your choice if you want to save $9. Great product, fast shipping. 294196
by: Gary Miller09/08/2016
The turn around on this order was awesome. I haven't instaiied it yet but it looks simple. I was a little disappointed that there was no mounting bracket with this, but no fear I'm going to bore a hole it the bumper and with some self tapping screws we will be up and running in no time. I'll post some pictures of the completed job. Thanks for your excellent service 292605
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

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: Kevin W.07/06/2015
The product I think is a very good quality made and works super, by this I mean it all fits wonderful like it suppose to. 209801
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: Dave I.02/01/2017
The harness I purchased for my 2002 Ford F-150 was fine with no problems installing it. However, it did not solve the problem I had (no right stop/turn signal and no running lights). I suspect the problem lies elsewhere and is no fault of the new harness. 337573
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: Ron C.06/10/2016
I have purchased and installed a 7way trailer plug wiring harness for my f150 it was super easy to install and an exact fit. Basically just plugged it in to existing wiring and mounted the plug bracket that I ordered separately. Thanks etrailer! 259943
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
I mistakenly bought the wrong product the first time. I small print the first one said it was not for the Heritage body 2004 F150. I ordered the correct one and it worked great. The product should be better identified online. 324059
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

Item listing was very clear and the product was delivered very quickly! The video tutorials on your website are very helpful and helped me in my decision to purchase from eTrailer.com. Another Satisfied customer! 6639
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
