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.

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

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

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: Steve D05/25/2012
Wiring harness fit my F150 perfectly. Works great! Instructions were excellent; could not have been simpler....if only everything were this easy. 41727

Installed the 118427 wiring harness on my 2002 F150XLT followed the video on etrailer.com and it was just plug and play no problems. 171831
by: Austin J.06/18/2013
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

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: 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: Andrew M04/22/2015
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: 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: 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

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: Herb S.02/04/2011
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

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
by: Michael Price03/28/2011
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

I am sorry this is so late in coming, however I just completed the installation. The items as recommended by the person taking the order worked for a complete and easy installation. 130082
by: Russ S.03/02/2016
Very pleased. The harness and relays fit perfectly. Plug and play! After a year everything is holding up just fine and it's given me no issues so far. Couldn't ask for anything more. 239206
by: John T08/24/2015
Worked well with the bracket and parts that had to be ordered along with the harness. Whole process took less than 20 minutes and I am estatic with the results. Plug and play. 221435

This product is brilliant. the website made it easy to figure out how to do it and the customer service was first rate. I will be doing more business with these people. 149983
Plug and play; just like it says. No butt connectors under the bed of the truck. Everything worked out well. Must have product if you are wiring up for trailer brakes. 122351
