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:
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:

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:

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:
2019 Ford Ranger

Excellent all around. Thanks



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:

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



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:
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:

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

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:

Very simple installation. Works perfectly. Thanks etrailer again for great information

  • Will the Curt T-Connector # C56431 Fit with My OEM 4-Way/7-Way Plug on My 2022 Ford Ranger?
    Based on the photo you included for us, it looks like a standard connector plug. With that being said, the Curt T-Connector # C56431 will fit the plug you have. We carry very similar plugs to the one you have as part # HM40975.

  • Capacities of Available Curt and etrailer Class III Hitches for 2021 Ford Ranger
    According to the owner's manual, the 2021 Ford Ranger can tow a braked trailer weighing up to 7500 lbs with up to a 750 lb tongue weight. The Curt # C13417 and etrailer hitches # e63ZR have 6000 lb towing/900 lb tongue weight. Additionally, the towing capacites of the Curt and etrailer hitches increase to 8000 lb towing/900 lb tongue weight if you have a weight distribution system. I attached a video of these hitches for you to check out. Although you'll be limited to the 750 lb tongue...

    We have the parts you're looking for! It looks like Ford is using the Redarc Tow-Pro Elite, part # RED44FR, as the brake controller for a 2020 Ford Ranger. If your Ranger has a factory 7-way, then the harness you need to install this brake controller is the Plug-and-Play Harness, part # 331-TPH-007. This will allow you to easily hook up the Tow-Pro Elite. I've linked to a video review of this harness for you to look at. We also have the controller and harness bundled together, which I've...

    The Curt Trailer Hitch item # C13417 is a confirmed fit for your 2021 Ford Ranger Tremor. It is also the best hitch receiver we have available for your Ranger and I highly recommend it. This hitch is custom fit and attaches with included hardware with no welding required. It has a gross towing capacity of 6,000 lbs and a maximum tongue weight of 900 lbs.

  • Will Adding a Trailer Hitch and Wiring to 2019 Ford Ranger Increase Towing Capacity
    The towing capacity of a 2019 Ford Ranger in the eyes of the manufacturer cannot be increased even if you add the parts that come with the factory tow package like a trailer hitch (Curt Trailer Hitch Receiver part # C13417) and wiring harness (Curt T-Connector Vehicle Wiring Harness part # C56431). I will say however that a lot of towing packages come with just more than a hitch and wiring, usually some sort of additional/upgraded oil/fluid cooler. We do have options for these (Derale Series...

  • Does a Hitch From a 1990 F-150 Fit On a 2019 Ford Ranger?
    We do have a hitch that fits your 2019 Ford Ranger # C13417 but a hitch for a 1990 Ford F-150 does not fit a 2019 Ford Ranger because hitches are model year specific to every vehicle and need to have certain mounting points on a vehicle's frame to ensure a proper and safe fit. In addition to the trailer hitch, you will also need trailer wiring. The Curt T connector # C56431 is a great option for your vehicle. This unit is easy to install and it easy to conceal under the vehicle. We also...

    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.

  • Troubleshooting Lights With Hitch Cover and Curt Harness on 2019 Ford Ranger
    The issue is almost certainly with the hitch cover that you are using after you installed with the Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # C56431. A number of hitch covers have been known to wreak havoc with Ford trucks and cause faults in the dash when used so I recommend removing the hitch cover and the issue will abate.
