Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located beneath the rear of your vehicle, in the center just behind the spare tire. 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.

Plugged right into vehicle harness as advertised. My only thing is with my vehicle I ended up cutting off about 3/4 of the wire harness because I had a short distance from factory harness to the bumper. 640841

  • Adding a 7-Way Connector and Brake Controller to a 2018 Ford F-150 with Factory 4-Way
    I will be happy to get your 2018 Ford F-150 set up with a 7-Way trailer connector and a brake controller. The method for doing so that requires the fewest parts is to hardwire in the brake controller/7-Way. Since your truck already has a factory 4-Way connector you will just need # ETBC7 to add a 7-Way, retain the 4-Way, and have the parts needed to install a brake controller as well as run a 12 volt hot lead. If you do not already have a brake controller picked out I recommend the...

  • 7-Way Trailer Wiring Installation On 2016 F 150 XLT With Factory 4-Way
    On your 2016 Ford F-150 XLT, since your truck came with the factory 4 way flat, you will want to use the Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # C56307 to add those other functions. The Replacement Multi-Tow 7-Way & 4 Pole Trailer Connector # 74682 you referenced is for vehicles that already have the US Car Connector present, and that is not the case for your vehicle. If you want that US Car Connector, you can splice in the 4' Pigtail Wiring Harness...

  • Adding a 7-Way Connector to a 2015 Ford F-150 with Factory 4-Way
    If you follow the factory 4-Way wiring forward under your 2015 Ford F-150 you should find that it plugs into another harness that continues forward on the truck. The connectors there should be rectangular. If so then you can use # C56307 however there are a couple of things to be aware of. First, it is possible that everything is already wired up and ready to go on the forward connector but you may need to add fuses or relays to make it fully functional. To determine this you can check...

  • 7-Way Recommendation for a 2016 Ford F-150 XL with 4-Way
    For your 2016 Ford F-150 if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # 37185 and the install harness part # 22292. If you check out the install video I attached you will see how the connections would be made. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well...

  • Parts Needed to Install 7-Way on 2016 Ford F-150 with 4-Way
    To install a brake controller in your 2016 Ford F-150 you would be able to use the brake controller port under the dash and you will need to complete the wiring at the rear of your vehicle to the 7-way at the rear of the truck using the 4-way to 7-way adapter part # 37185. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.

  • 7-Way Recommendation for 2016 Ford F-150
    That's interesting that Ford installed a brake controller in your 2016 Ford F-150 but did not give you a 7-way to go with it as well. What you would need is the part # C56307. This will plug in line with the 4-way harness you have at the rear of your vehicle and will give you a fully functional 7-way.

  • Parts Needed to Install Brake Controller in 2016 Ford F-150 with 4-Way
    You are close to having what you need, but instead of the Curt harness part # C56307 you would want the part # 37185. This will convert the 4-way to a 7-way and will allow the P2 part # 90885 and the install harness part # 22292 to install easily. There will be a few connections you need to make under the rear of your truck that you can see in the install video and help article I attached for completing the wiring to the # 37185 but the # 22292 plugs in under the dash of your truck.

  • Recommended Best Trailer Hitch Receiver Option For 2015 Ford F-150 XLT
    For your 2015 Ford F-150 XLT, I recommend the Curt Trailer Hitch Receiver - Custom Fit - Class IV - 2" # C14016. This will give you a 2 inch receiver for the most variety of accessories and choices for ball mounts. It has an extremely strong rating of 1000 lbs tongue weight and 10,000 lbs towing, which will exceed your vehicle capacity. You will be limited by the capacities listed in your owners manual and not by the parts attached. For your vehicle wiring, your truck either came...
