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 (260 Customer Reviews)
I have a 2003 F-150 and wiring parts I needed were a perfect fit. The videos were very helpful and informative. Now i know that there are relays and fuses that control trailer lights even through the truck lights are working fine.
Products are great and the customer service is even better! I recently purchased some things from etrailer for my 1998 Ford F-150. Delivery was on time like promised but when it arrived the box was heavily damaged. To top it off four out of the five products that I ordered were not even in the box. UPS driver told me that’s all that he had for me and also told me to reject the delivery and he loaded the damaged box back into the truck.
I called customer service at etrailer and explained what had happened. They gave me the option of my money back or re-shipping. I chose the re-shipping. The delivery was made again and this time everything was there and no damage! Thank you etrailer for your excellent customer service. I will never go anywhere else for my trailer/towing needs.
This is exactly what I needed. It plugged directly into the factory harness and my existing 7way/4way factory receptacle.
The product was exactly what I ordered.... great instructions.....easy to follow instructions....product has been working awesome.....
Wayne D - 03/16/2022Excellent 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.
Austin J - 06/18/2014Great quality product and easy to install. Thank you
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 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.
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.
Rachael H - 03/29/2018Perfect fit, easy to install. The installation videos for each item were very helpful. Very competitive prices.
Very easy to install! Is actually the proper part unlike local places I tried. Customer care was fantastic with questions about shipping.
EXCELLENT CUSTOMER SERVICE, FAST SHIPPING AND AT A GOOD PRICE. HIGH QUALITY PRODUCTS AND SPECTACULAR SUPPORT. GOOD FOR ALL THE PERSONNEL THAT PARTICIPATED IN THE PROCESS OF RECEIPT OF ORDER, INVOICING, PACKAGING AND SHIPPING. CONGRATULATIONS FROM PUERTO RICO! YEEAAAHH!
Haven't had any problems with this at all. Plugged right in and worked every time
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 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.
Quick and easy install` all plug and play wiring harness. Took about an hour with no problems. Great product and great company.
Trailer conector has worked perfectly on my 97 f150. I pull my boat or utility trailer with it weekly. Lights always work no issues
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.
This wiring harness fit perfectly and plugged right into the factory trailer harness. took about 30minutes, only because the factory harness was a bear to get apart after 20 years of road grime on it. :-)
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!!!
Makes the second vehicle that I’ve installed the custom made wiring harnesses and controller on using etrailer parts. All items were a prefect match for the vehicles just like advertised. Support from their experts was timely and accurate. Products are well made for great. Will continue to use them.
Good quality, painless plug in installation. the only complaint I had was 2 maxi blade fuses were provided instead of the cartridge type 30a my 01 F150 needed
Just what I needed to add trailer brakes to my 01 f150. Plug and go installation. Heavy wires and quality plugs. Came with needed relays . Just pop them in the junction box under the hood and good to go. Install video made it simple. Delivered sooner than expected.
The product itself was as expected. However, the example I received was clearly an open-box and was missing the clip that retains the harness in the 7-way connector.
