Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver side rear bumper. After plugging in the connector, route the 7-way end of the harness along the inside of your bumper toward the center of your vehicle.


Once installation is complete, the 7-way connector will be stowed beneath your vehicle, near the trailer hitch. If necessary, secure the harness with the provided cable ties.


It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 7-pole connector itself - to help prevent corrosion.

Great products easy installation



by:

It fits like a glove. Plug and play 35 minutes tops with everything. The only bad thing the zip ties were short. But I'm satisfy with the product and I would recommend it.



by:
Ford Ranger

It worked as described. It arrived very fast. I had it installed in about an hour. My 2021 Ford Ranger is HAPPY.



by:

My installer was very happy I bought the wiring harness from only had good things to say about it. Works great and easy to connect to rental trailers and my trailers.



by:
2020 Ford Ranger

I found it very easy to install, however it did have a lot of extra wire to role up. I did order the HM40975 connecter and installed in the factory postion on the back bumper. the only problem is that my 2020 RANGER came with a 4 pin connecter, but not the factory tow package.So it is missing 3 wires in the wire harness in the truck and only the 4 pins work. I will have to add the other 3 wires myself some time, as I want to get a camper that needs all 7 pins to work.



by:

Harness looks like a factory install. Very good instructions.



by:
2019 Ford Ranger

I remember when things weren't plug and play. Those days sucked, lol. Super easy install. Unplug the factory harness, plug in this jumper harness between. On my 2019 Ranger there is a factory cut out in the bumper for a 7-way. So, I used a 1.5" hole saw to make an opening in the plastic bumper cover to flush mount the plug and give it a factory look. Gave it four stars because I'm a stickler for good directions and these didn't specify what the white wire with the ring terminal end is or where to attach it. I know what it is, but what if I didn't?



by:

This works well and was a fairly easy install. What's excellent is the eTrailer Customer Support. My first one started throwing errors (when breaking, accelerating, etc) with no trailer hooked up. The eTrailer folks had me try a couple of troubleshooting steps, then shipped me a replacement right away (it was about two weeks from warranty expiring!). This was the 4th vehicle I've outfitted with hitches, wiring, etc from eTrailer. Always great service. Won't shop anywhere else.



by:
2020 Ford Ranger

Fast delivery



by:

Easy to use and super easy to install. Not many options for the Rangers, but, this worked exactly as needed. Didn’t need a bracket, I used the stock location in the rear bumper. I drilled it out, drilled the factory bumper back plate and ran 2x 1/4-20 machine screws through it.



by:

Paid extra for fast shipping and took as long as the free shipping



by:

Put this kit on my 2020 Lariat ranger. Only complaint was the supplied self taping screw broke off when trying to install and the zip ties was to short. Everything else was very simple easy install. I wanted a factory look so I ordered the Hopkins 7way/4way plug separately.



by:

The quality of the product was good but service was etrailer customer service was horrible. I ordered a hitch and a wiring kit with free shipping. They shipped the hitch, but not the wiring harness as it was out of stock, although when ordering it confirmed that it was in available. There was an alternative for a few dollars more. I had to purchase the comparable item on a separate invoice and pay shipping on it. Contacted the company with no response back. They should have contacted me before shipping and offered the alternative item, or shipped the other item with free shipping. Again, happy with the product, but not the customer service.

I am sorry to hear you had such a disappointing experience. It seems that our customer service department has issued you a credit as a courtesy for your situation.



by:

The connector worked great for my truck.



by:
2020 Ford Ranger

Worked perfectly. My 7pin socket was in very close proximity, so I coiled a pile of wire up. I installed a bumper mounted socket, Ford Part # FU5Z-14489-A versus using the supplied scoket, and the wiring plugged right in. Nice product. I installed my trailer brake controller and this finished it out.



by:

Easy to attach, instructions plane and simple. Item works great no problems.

Its working good



by:
2022 Ford Ranger

The Curt T-connector surpassed my expectations on ease of installation for the plug. The socket part however was a little more time consuming because I decided to mount it in the factory cut out position in the upper bumper instead of utilizing a separately purchased bottom bracket under the bumper..still relatively easy.



by:

For a vehicle specific harness, it’s way longer than it needs to be. There is an unterminated ground wire that’s like, why? Why not terminate that wire against weather? Also, no instructions as to even why it’s there or what to do with it. I hope I’m right in deducing it needed to go to chassis ground, that’s what the wiring diagram I found online indicated. At least the connectors are correct.



by:
2019 Ford Ranger

Excellent all around. Thanks



by:
2020 Ford Ranger

This item was just what I needed I had the Sleeve from Ford but no cable or plugs to install under the truck bumper and this fit right into the factory wiring for my New 2020 Ford Ranger. If you don't have a 7 way trailer plug this kit will fit! Thanks!!



by:

Worked perfectly. plenty long enough to putvconnector where i needed it



by:

This would get 5 stars if it came with the OEM 7/4 way connector. All Rangers have a place on the number to install that type of plug, but this comes with an oddball that needs an extra bracket to mount to the hitch. I bought the right plug and now have one I don’t need. Otherwise it’s easy t9 install and works just as it should.



by:
Ford Ranger

This is one of many orders I have placed with etrailer.com. I purchased this for my Ford Ranger. Perfect fit the first try. If you need trailering items for your truck, boat, Jeep, or motorhome this is the place to shop.



by:
Ford

Easy to install! I bought a Ford Motocraft OEM 7pin & regular connector that was Oval shaped to fit the punch out in my bumper. Worked great and was a seamless install!



by:

The hitch went in without a hitch.The wiring harness plugged in easily. The mounting bracket for the plug-in didn't match the holes but a drill took care of that. Less than 45 minutes to install! All in all, nice.

  • How To Install Redarc Tow-Pro Elite In 2019 Ford Range Without Factory 7-way Connector
    Thank you for purchasing the Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # C56431 through us! You can absolutely install the Redarc Tow-Pro Elite # RED44FR on your 2019 Ford Ranger. While there is not a factory trailer brake controller port, Ford did run the wires needed under the dash. You should find a bundle of 4 wires with blue tape near the driver side wheel well underneath the dash. The 4 wires should be blue, yellow/red, white/purple and white. You will...

  • 7-Way and Brake Controller for 2019 Ford Ranger without Trailer Wiring
    Since plan is to install a brake controller too the 7-way kit you'd want for your 2019 Ford Ranger is the part # 22124 which comes with brake controller wiring unlike the Curt you mentioned. Once installed you'd be able to install a brake controller like the Prodigy P2 part # 90885 which is one of our best performing and most reliable brake controllers.

  • Will The etrailer Trailer Hitch Receiver Fit With Larger Spare Tire On 2021 Ford Ranger Tremor?
    Yes, the etrailer Trailer Hitch Receiver # e63ZR will fit your 2021 Ford Ranger Tremor. I have included an image sent in with a review showing the Curt # C13417 which is identical in construction to ours with the larger spare tire used on the Tremor. The Curt T-Connector Vehicle Wiring Harness # C56431 will provide you with a 7-way connector which you can mount using a Bracket # C67UR. If you need it to tow a smaller trailer you will need an Adapter # PK12716.

  • Best Way to Install 4-Way/7-Way Wiring Harness on a 2019 Ford Ranger
    Sounds like you've done a great job at installing the Redarc Tow-Pro Elite # RED44FR, and that you're on the right track when it comes to installing the Hopkins Endurance Multi-Tow Plug # HM47180 on your 2019 Ford Ranger! To wrap up your installation I actually recommend picking up the Curt T-Connector Vehicle Wiring Harness # C56431 and then removing the 7-Way plug and replacing it with the Hopkins 4-Way/7-Way since they both have the US CAR connector at the back. Simply unplug the Hopkins...

    It sounds like your 2022 Ford Ranger XLT may be missing or have damaged fuses/relays for the trailer functions.

    Yes, we do have both. I recommend using the etrailer Trailer Hitch Receiver # e63ZR on your 2023 Ford Ranger. This receiver is made in the USA and comes with a lifetime warranty. It is rated for up to 6,000lbs trailer weight and 900lbs of tongue weight. If you are using with a weight distribution hitch trailer weight increases to 8,000lbs.

  • Does 7-Way of 2022 Ford Ranger Fit 7-Way of Casita
    The SAE number you listed J2863 is for a standard RV 7-way blade connector like what Casita would use for their trailer wiring connectors. We've not had any issues with the Ford 7-ways and the ones that would come on a Casita. If you ever needed a replacement on your Ranger the part # HM40940 would plug right into the connector on your vehicle. Or for a new harness and 7-way you'd want the part # C56431.

  • Do The Towing Capacity Differences of Curt and etrailer Trailer Hitches For 2021 Ford Ranger Matter
    I looked up the capacities of your 2021 Ford Ranger and found that as long as the trailer you are pulling has trailer brakes then your truck will have a maximum towing capacity of 7,500lbs. The Curt # C13417 and etrailer Trailer Hitch # e63AR actually have the same towing capacities. They only have a 6,000lb trailer weight rating and 900lb tongue weight rating. The towing capacities increase to 8,000 pounds when used with weight distribution, so they could limit how heavy of a trailer...

This custom-fit T-connector plugs into your Ranger's wiring harness, which is located behind the driver's side rear bumper. I recommend using the No-Drill Mount Bracket item # 18136 and the item # C67UR to secure the 7-way connector to your hitch. This will put it in an easy to reach spot and prevent...

  • Will Curt 7-Way for 2021 Ford Ranger Work with Boat Trailer with Surge Brakes
    Your boat trailer has "surge brakes" which use the inertia change of you hitting the brakes to pressurize a master cylinder and apply hydraulic pressure to the brake assemblies to slow the trailer down. So you don't need a brake controller like you mentioned and all you'd need for a 7-way is the part # C56431 that you referenced.

The 7-way kit part # C56431 is also the correct kit to add 7-way to your truck and then the # HM48625 is the correct kit to secure it.

The Curt hitch # C13417 has a traditional glossy black finish and the etrailer hitch # e63ZR has a modern matte black finish. Otherwise, their capacities and installation are the same.
