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.

Just follow the wire diagram when installing. Worked as intended.



by:

Works exactly as described. It wasn't too difficult to install either.



by:
2015 Ford Explorer

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.

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.

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



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



by:
2016 Ford Explorer

Easy install , looks great.



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!



by:

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



by:
2015 Ford Explorer

Worked perfectly for my 2015 Ford Explorer Police Interceptor!



by:

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.



by:
2017 Ford Explorer

Shipping was fast, did not realize the mount bracket was not included. Now I have to pay shipping for a 5 dollar part when it could have been part of my original order.



by:

This trailer was exactly what we were looking for. Well built and the price was very affordable. Good job by sales rep too.



by:

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



by:

This harness is a plug and play type no cutting of wires. Easy install. Service and delivery time from trailer was great as usual. Excellent company to do business with and good prices too.



by:

This was a good installation, I would recommend, if you are mechanically inclined then install it yourself.



by:
2016 Ford Explorer

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.



by:

Perfect fit, easy installation

  • Recommended 7-Way Connector And Trailer Brake Controller For 2018 Ford Explorer Without Tow Package
    I would be happy to recommend everything you will need to add a 7-way connector and trailer brake controller to your 2018 Ford Explorer Limited without the factory tow package. 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. When we did this install on a similar 2017 Ford Explorer we used the...

  • 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.

    I have a super easy brake controller solution for your 2017 Ford Explorer with the Curt Echo brake controller part # C51180 which plugs into an active 7-way and once synced to a smartphone is ready to tow. For an easy to install 7-way kit all you need then is the part # C56306 which plugs into the square trailer wiring connector at the rear of your vehicle. I attached an install video for this that shows it installed on a 2017 Explorer just like yours. Other installs will require hardwiring...

  • 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...

  • Trailer Wiring and Brake Controller Recommendations for a 2017 Ford Explorer Without OEM Tow Package
    To get your 2017 Ford Explorer (without the factory tow package) fitted with a brake controller I recommend installing the following: Curt T-Connector 7-Way Trailer Connector - # C56306 Mounting Brackets - # 18138 and # C57202 (to secure the 7-Way to your hitch) Curt Echo In-Line Wireless Brake Controller - # C79DR According to my research the wiring for towing a trailer exists whether you have the tow package or not, but to install a brake controller you might need to cut and splice...

    The etrailer Trailer Hitch Receiver # e98867 is the correct receiver for your 2018 Ford Explorer. This class III 2" receiver is rated for 400lbs of tongue weight and a trailer weight of 4,000lbs. With a weight distribution hitch capacities increase to 500lbs of tongue weight and 5,000lbs trailer weight. The wiring is where things can be confusing.

    There are a few ways to go add a trailer brake controller to your 2015 Ford Explorer without the factory tow package. The easiest way and the option I recommend is replacing your aftermarket 4-way connector with the Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # C56306 which will plug into the factory connectors in your Explorer and give you a 7-way connector. Then for a trailer brake controller I recommend the Curt Echo Wireless # C51180 as it plugs directly into...

    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...

    There are many different wiring harnesses on Police Interceptors, and the photo you've attached is not a common fit for trailer wiring. I don't believe that harness is for your trailer wiring even though it looks similar. I've attached two other photos to show you what the harness should look like and the connection that you will be making.

  • 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...

  • Difference Between The Curt C56278 And C56306 For A 2015 Ford Explorer
    There is very little difference between the Curt # C56278 and the # C56306. Even the instruction manuals that they come with are identical. The only difference I noted is that the # C56278 is listed for 2011-2015 Ford Explorer, and the # C56306 is listed for 2011-2019 Ford Explorer. So the C56278 would have been the first model that Curt made, then the # C56306 cam along after. Other than that they are identical even down to the wire length and color.

    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.

    I would be happy to help you find all the components you need to tow with your 2017 Ford Explorer.

The Curt 7-way Connector # C56306 you installed in your 2014 Ford Explorer is not set up for a trailer brake controller, but using Wiring Kit # 5506 you can change that.

  • 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. If your vehicle does not have the towing package, I cannot recommend to tow a trailer that exceeds the capacity of the Explorer because it will cause damage to the vehicle's frame and transmission...

  • How To Know If Your 2017 Ford Explorer Has A Tow Package
    You can determine if you have a tow package by reaching out to a Ford dealer or by checking the undercarriage of Explorer. If it does have the tow package there will be a trailer hitch receiver and either a 4-pole or 7-way wiring harness visible as well. If not, you can install the etrailer Trailer Hitch Receiver # e98867 and Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # C56306 and you'll be ready to tow.

  • Recommended Hitch and Weight Capacity for a 2017 Ford Explorer
    What we always tell people to do is go off of what your manufacturer recommends. When they say 5,000 lbs with the proper equipment this could mean options like upgraded suspension or a transmission cooler. This doesn't necessarily mean a specific hitch or its mounting placement. The best way to find out your Explorer's accurate towing capacity is to have a Ford dealership run your VIN so they can see what options yours has.

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...

However, the 7-way kit # C56306 for vehicles with the factory towing package does include a 12V power feed. This too plugs in behind the passenger side rear tire.
