Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located beneath the rear of your vehicle, along the passenger's-side frame rail. 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. Use a mounting bracket (18138 - sold separately) to keep the connector secure. Note: Drilling may be required.


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.

The product works as described and appears to be quality construction, however the wiring information is imprinted incorrectly on the connector vs the paper instructions. You need to follow the wiring diagram on the paper instructions and ignore what it says on the connector itself. SEE PHOTOS

by:

The wire diagram was not correct and luckily I have knowledge of trailer wiring and had to make some adjustments to wire posts. Also there were no mounting bracket or bolts. I wouldn’t mind paying a little more if that was in the kit. Other than that it is quality made. Plug to vehicle was very simple but other side was difficult. 2 hours installation

Wiring harness fit perfect and had plenty of length to place the plug where I wanted it. I have several Ford Explorers in my fleet and this has been the go to place for parts.


Comments
This harness fits and works perfectly. Hardest part was cleaning the OEM connector of all the road grime on it.

This is the second Hitch i purchased from your company I noticed how well it was made The wiring harness easy to install directions are great the wiring is put together well

Good fit. Good quality.



- C56306
by:

Kit was fairly easy to install, but the one issue I did have was that you need to IGNORE the color-code markings on the connector itself, and ONLY follow the wiring diagram that comes with the kit! It was a bit confusing to see that the wiring pattern given on the directions was different than what was marked on the connector. Follow the directions for your specific vehicle, and you should be OK!

Works correctly although there was no wireing instructions with it and the package was open inside the box they sent it in. I would buy it again but I feel like it should have had some instructions at the very least.

Instructions were well written, I was able to install the harness without issue in about 30 minutes and so far it works great.

Trailer seem to never pinned out right so this allowed me to not only pin it the way I wanted, but it allowed me to use ilets that would be a lot more robust. I was happy with the quality and how easy it went on.

  • Troubleshooting Trailer Wiring Connection on 2014 Ford Explorer
    Thanks for the photo. We don't have anything that is compatible with the harness you show. I believe you disconnected the harness that should be right next to the trailer wiring harness. Please see attached video at the 1:33 mark. If you don't have that alternative harness then you don't have then you will need to use the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM40285 instead of the # C56306 in the video. If that is the case you will then...

  • Trailer Wiring Harness Compatible with 2014 Ford Explorer
    With just the one connector you referenced, the Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # C56278 or the # C56306 will work well. I've attached a video that shows this installation with just the single connector to assist. You may want the Curt Mounting Bracket for 7-Way Connector Plug # C67UR along with the Curt No-Drill Bracket # C57202 to complete your installation.

  • How to Install Trailer Wiring Harness on 2015 Ford Explorer Police Interceptor
    I would say that it's entirely possible that since this is a police interceptor model that there just isn't a plug in for a trailer wiring harness on the vehicle anywhere; however I do believe this is unlikely. I would look on the driver's side (assuming that you haven't already). If you absolutely cannot find any type of wiring harness towards the back of the vehicle, then you've potentially got 2 options. The first would be the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole...

    The Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # C56306 is a direct fit into your factory wiring on your 2018 Ford Explorer without factory tow package. It does not however give you the ability to mount a brake controller under the dash of your vehicle with a simple wiring harness. You would need to splice in the wiring kit # 5506 and add a brake controller with that hardwiring. Your other option is to use the T-One Vehicle Wiring Harness with 4-Pole Flat...

It's either going to be found behind the glove box on the passenger side or it's going to be located to the left of the steering column under the dash taped to another harness near the emergency brake pedal. The part # 3035-P is designed to fit this port and install a brake controller like the very popular P3 part # 90195. The Curt Echo part # C51180 that you mentioned is a really great option. It's...

  • Troubleshooting Running Lights Issue During 7 Way Connector Install on 2018 Ford Explorer
    It sounds like you're having an issue with the installation of the 7 way connector that came with the Curt # C56306, and we can absolutely help you get this resolved. I'll start off by saying that the wiring colors are going to be a general guide and not every vehicle manufacturer uses the same colors of wires, but since this is a plug and play harness the colors on the vehicle won't matter and you should have the correct connection coming from the plug. Since this is a new installation...

Starting with the 7-way connector I recommend the Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # C56306 which will plug into the factory trailer connector ports underneath the bumper on the passenger side of the vehicle.

    The Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # C56306 you asked from is a fit for the 2011 - 2019 Ford Explorer without factory Tow Package. Based on what you mentioned it sounds like the trailer wiring isn't working correctly. The next step is to check your connections to make sure you don't have any bent pins. It sounds like the ground connection may be the issue if you are getting connections on the pins as you check them using a circuit tester like the...

  • Which Wiring Harness Do I Need for a 2017 Ford Explorer
    The wiring harness you'll need won't be affected by the actual hitch, but will instead depend on the trailers you plan on towing with your 2017 Ford Explorer. If you're going to be towing a trailer without brakes, then the Tekonsha # 118540 will provide you with the harness you need. This is designed for Explorers that did not come with the factory tow package and will tee into the wiring at the rear of the vehicle on the passenger side.

  • Can OEM Exhaust Hangers be Reinstalled with Curt Hitch on a 2013 Ford Explorer
    The way the Curt Trailer Hitch 13100 (replaced by part # C13386) installs would interfere with the OEM exhaust hangers which is why they need to be removed. If you're missing the hardware for the hangers then you can either get them replaced with part # RHK which is a whole hardware kit, or you could source them locally.

  • Recommended Trailer Wiring Harness for a 2018 Ford Explorer Without Trailer Hitch
    The trailer wiring harness options for a 2018 Ford Explorer can be narrowed down to two categories, models with the tow package and models without the tow package. If you don't have a trailer hitch then you won't have the tow package therefore I recommend using the Curt T-Connector Vehicle Wiring Harness part # C56172 if you only need a 4-way or part # C56306 for a 7-way. These options are both plug-n-play. That said, you'd also need a trailer mounting bracket to install either option,...

  • Parts Needed To Tow 3,000 Lb Trailer With 2015 Ford Explorer
    You can add a hitch, weight distribution system and cooler to the 2015 Ford Explorer but it will not increase the towing capacity set by Ford for your particular vehicle. It is not possible to increase the towing capacity of the vehicle by adding parts unless they came on the vehicle from the factory.
