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.

Easy to install, and worked great until I backed into a concrete light pole support. I needed a new socket end where the trailer plugs in, as original was smashed up and spring cover wouldn't close right. etrailers on-line chat was worthless to try and find a direct fit w/o having to buy a whole new kit. I researched it myself and took a chance and ordered two (2) of etrailers Pollak Replacement 7-pole, RV-Style, Trailer Connector Socket-Vehicle End-PK11893 (Pollak PA66-GF30). This is a perfect replacement for the original that came with this 118242 harness kit. Bought 2 to have spare for next back-up incident.....
Service (Jamie) was awesome very knowledgable and fast ! The post office on the other hand it sat there for four days . I recommend ups or fedex or some other delivery source !
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.

Still working flawlessly, the factory 4 flat isnt working but this one still works like it did when brand new. Highly recommended.
I installed the wiring on my Ford F250. I've had the wiring for about a year with zero problems. The wiring package had everything I needed for a complete installation. It was easy to install. We've towed our RV over 6,000 miles since the installation. The harness has held up just fine in all types of weather and climates. Also, hats off to Kennika for her exceptional customer service.
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.
The tow package I purchased last year, fits great and installed perfectly. It works perfectly with my electronic under-dash brake controller.
The kit came with everything that I needed and instructions were easy to read I had the entire kit installed in about 40 minutes it's work Flawless for me for over a year and I tow a variety of trailers the plug is never failed due to workmanship it is still water tight.
The receiver cap spring still has excellent tension to help hold the plug into place, the only gripe I have is that I should have installed stainless mounting screwswhen I installed the kit because the mounting starting are starting to rust a little, but that's my oversight and is nothing to do with the kit and its ability to provide flawless service.
I highly recommend this product if you're like me and was looking for an oem Plug and Play setup!
5 stars!
My truck already had 7 pin harness but had a ground issue. Replaced it with this one and it works great now. Plugged right in but had to leave old harness in to get taillights to work. Way less expensive than buying OE harness from Ford
Thanks etrailer

One year and many trailer miles later, plug is still working perfect. Thanks
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.

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 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

Still loving it works great
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.

Thanks for your review and your purchase, Dave! Often, the culprit is a kinked wire on the trailer or a bad ground. To assist you in troubleshooting your trailer wiring, I have included a link to our help article.

I was unable to find the problem I was having and ended up removing the harness and just tapping into the trucks lighting system with a smaller, basic harness I already had. But Ill give you an A plus for customer purchase follow up - very nice to see nowadays!
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.
7 Pin wiring harness for my '02 Ford F-150 was a 15 minute job, easy to install without removing the spare, and worked immediately. Thanks!

It works great. I’ve used it quite a bit during the year. Thanks
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.
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.

The product is doing fine.
Super quick mailing and exactly what I needed. Wiring is holding up fine after a years usage.
Product does EXACTLY what its supposed to. Do no purchase an aftermarket product as they do not work (already tried) - but this product worked like a charm and continues to work. Good product worth the money.
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.******
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.
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!
This kit was exactly what I needed for my '03 F150 to pull my trailer. It was simple to install and nothing additional was needed in my case. The connectors are usually already there if you have the tow package and a 4-pin. Just remove the spare and the connectors are there and it was simple as pie from there. etrailer is the best place for all your needs and I would highly recommend them to anyone needing parts or supplies for their towing needs. Great products, great company!
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.
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.
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.
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.
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.
