Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C56110 Review

Today we're going to be taking a look at part number C56110, this is your replacement OEM wiring harness. This product is going to fit certain years of the Ford F150 and the E series vehicles. It's going to supply your 4 way flat plug at the back of the vehicle. Now, this is designed to be an exact replacement for a damaged, or needing to replace OEM wiring harness. Here on the 4 way flat, it's going to come with the protective cap, that way you can protect your connection points when the connector is not being used. Just goes over that area there, and then comes over the connectors.

It's also going to come with your detailed instructions, it's going to come with your cable ties to secure any excess or lose wires that you may have, and it's going to come with self taping screw to make a good ground connection right here with the ring terminal, and white wire. Very easy installation, you do not have to worry about cutting or splicing any of your wires. All you have to do is locate the OEM trailer wiring harness connector on top of the spare tire support, it's usually located on the driver side, it favors the driver side. You're going to insert the new connector. The connector should match up perfectly, make sure it's fully inserted, it's going to lock and secure into place for a nice, tight, secure connection. Then you're going to need to make a good ground connection using an existing screw with the nut, or you can use the supplied self taping screw.

Place that right here through the ring terminal that's attached to our white wire, which is our ground wire. Once you have that connected you can then route the 4 way back to the rear of the vehicle, and then you can secure it in a convenient, out of the way location, near the hitch. Again, detailed instructions, these are going to have pictures that are going to help you through the installation process, very detailed. Once you have that done you can go ahead and use some of the cable ties to secure the wiring, keeping it up and out of the way. That's going to do it for today's look at part number C56110.

This harness for my Ford F-150 was a perfect fit. When I bought my truck it had a hitch but no light harness and everywhere local wanted $50+ dollars. This was an excellent price and so easy to install. Took me a few minutes. All you need is a power screw driver to screw the ground wire down and plug in the harness and that’s it. Definitely recommend this to anyone!



by:

I can not be happier with the service and product. I received the Draw Tite Class III trailer hitch on time as expected. From start to finish and by myself, it took me exactly 15 minutes to install. I did not need to lower spare tire and it looks clean and neat on the truck. It took me longer to open the cardboard box. Thank you for your great service and follow up and I will highly recommend you in the future.

Happy with your wiring harness good prompt delivery will use for future purchases.

  • Fit of Curt C56110 Replacement 4-Pole OEM Trailer Wiring Harness for 2016 Ford F-150
    According to Curt Manufacturing, the # C56110 is a fit for 2010-2020 Ford F-150 models, so it will indeed work on your truck.

  • Recommended Replacement Trailer Wiring for 2018 Ford F-150 Without Tow Package
    If you have the factory 4-way, then you simply need the Replacement OEM Wiring Harness for Ford F-150 # C56110. If you have the factory 7-way then I recommend the Reese Multi-Plug Wiring Harness for Factory Tow Package - 7-Way and 4-Way Flat Trailer Connectors # 74682. Your truck will have either the rectangular connector or the round connector already present. These will simply plug into the factory wiring which is present even without tow package and you will be good to go.

  • Best Way to Convert 4-Pole Trailer Connector on 2014 Ford F-150 to a 7-Way Type
    I do have a solution for you to convert your factory 4-pole trailer connector to a 7-way RV-style type on your 2014 Ford F-150 but there is no plug-in harness that will connect where the 4-pole does. Instead you'll use our kit # ETBC7 which includes the 7-way socket, wiring, connectors, circuit breakers - everything you need to adapt the 4-pole to a 7-way with its additional circuits for brake power, 12V trailer power and reverse light signals. Just for reference, the linked photo shows...

  • Boat Trailer Lights Sometimes Work and Sometimes Do Not When Connected to 2010 Ford F-150
    It sounds like the connector on your truck may be corroded or there is a loose connection from the vehicle side connector to the boat trailer. I would begin by checking the vehicle and trailer side connector for corrosion, if there is corrosion you will need to replace the connector. Next, you will want to check to make sure all the lights on the trailer have a good ground to a clean metal surface. If you are using a plastic license plate holder, this make be preventing the left light...

  • 4-Way Mounting Bracket Recommendation for Replacement 4-Way for 2015 Ford F-150
    For a 4 way mounting bracket to hold the 4-way connector of the part # C56110 I would recommend the # 18144 and the # C57202. The # 18136 will attach to the crosstube of the hitch and then the # 18144 will attach to it to provide a bracket. I attached an install video for you to check out as well.

  • Wiring Harness for 2016 Ford F-150 Without Tow Package
    To help you determine which wiring harness will work on your 2016 Ford F-150 you can look for the connector that's under the truck's bumper. If the connector is round and looks like it will match up with picture # 1 that I've attached then you can use # 74682 and plug it right in to give you both a 7-way and 4-way trailer connector. If you find a connector that is more rectangular like in picture # 2 then you can use # C56110 which will give you a 4-way connector. If this is the case...

  • Recommended 7way Trailer Plug for a 2014 Ford F-150 That is Prewired for a 4way
    I can help you convert your 4way to a 7way on your 2014 Ford F-150. Since your vehicle is equipped with a factory 4way plug you will first need the Curt harness # C56110. To get a 7way for your trailer needs I recommend an adapter like the # ETBC7. This will allow the 4 way to plug into the adapter then you will need to run a few more wires to to gain the other functions of the 7way. It may be possible to use your current 7way if you snip off the round connector and use butt connectors...

  • Parts Needed to Tow 30-Foot/6500-lb Trailer with 2010 Ford F-150
    First you'll want to check your Ford owner's manual to confirm your particular truck, with its specific mix of cab style, engine, transmission and suspension components, has the required towing capacity for your 6500-lb trailer. If you cannot verify this in the manual your local dealership can look up the truck's VIN to confirm its tow rating. I checked the online manual for the 2010 F-150 and on pages 256-258 the towing capacities of the different configurations are listed. Trailer weight...

  • Reverse Light Recommendation that Easily Plugs into Trailer Wiring
    We have the Light Buster Backup and Utility Light for 7-Way RV Style Connectors # C8020 which plugs into the 7-way trailer wiring connector you have at the rear of your vehicle and will give you a brighter lighting when backing up at night.

  • Left Hand Turn Signal Causes Multiple Lights to Illuminate on Trailer
    The issue you are having with your trailer lights could be caused by either a ground or wire short. I first recommend you test the pins inside the 7-way on your tow vehicle to make sure that the issue is on the trailer and not the tow vehicle. The pins should only be active when you have the respective signal applied. For example, if you were testing the left hand stop/turn pin then the circuit should only be active with these signals applied. In addition to this, the turn signal should...

  • Troubleshooting Trailer Light Functions Not Working on 2014 Ford F-150
    On your 2014 Ford F-150 if you don't have factory wiring, you will simply splice into the tail light wiring at your tail lights to get the 4-way functions using # C58044. If you have the factory 4-way, then the harness may be bad or need help connecting. The Curt # C56110 is intended as a factory replacement for your truck. Make sure all the pins are not bent and the connection is free of debris or corrosion. If you have the factory 7-way, you will want to check your factory wiring...

  • Troubleshooting Factory 4 Pole Trailer Connector on 2013 Ford Edge
    It's possible that you've got some blown fuses or relays in the distribution box under the hood. Check fuse locations 37, 53, and 63. If you have blown fuses, it's likely they were blown by short circuits in the wiring of the trailer towed by the previous owner. If the fuses aren't the issue, rather than tracing the trailer wiring from the rear of the vehicle up front, you'll be better served by just abandoning the factory setup and installing an aftermarket trailer wiring harness like...

  • Recommended Wiring and Trailer Brake Controller for 2016 Ford F-150 without Tow Package
    If your 2016 Ford F-150 does not have a factory connector at the rear of the truck, you will just want to take a look under the bumper to determine which harness will fit. If you find a round connector that looks like the #1 image attached below, then I recommend the Reese Replacement Multi-Tow 7-Way & 4 Pole # 74682. This will plug directly into that round port to give you both a 7-Way and 4-Way connector. If you instead find a rectangular connector under the rear bumper, you will need...

  • No Power To Brake Output Pin On 2014 Ford F-150
    The first thing that I recommend you do to test the brake output circuit on your 2014 Ford F-150 is turn the power settings up to max on the brake controller, have a friend apply the manual override, and test the 1 o'clock pin on the 7-way. If you don't get 12 volts then you will need to sever the brake output behind the brake controller and test again for power with the manual override applied at full power. If you don't get 12 volts then replace the brake controller. If you do get 12...

  • Recommended Installation Kit For 2015 Ford F-150 For a Brake Controller
    I assume you have a 4-way connector at the back of your 2015 F-150. If so you will need part # ETBC7. This plugs into the 4-way connector and with additional wiring will give you a working 7-way and 4-way trailer connector at the back of your truck. I have attached a drawing that shows how the wiring is done for the # ETBC7. When working with electrical connectors I recommend using dielectric grease like part # 11755. This keeps dirt and moisture out of the electrical connections and...

This item and the similar Hopkins part # HM11140735 plugs in at the rear of the truck with a rectangular plug. Please refer to the linked photo. If instead your truck has a round U.S Car type connector you can use Curt # C55774 which includes both 4-pole and 7-way type connectors on one product.

  • Wiring Harness and Ball Mount Recommendation for a 2018 Ford F-150
    The Curt Trailer Hitch # C86HR is an excellent choice for your 2018 Ford F-150. Then for wiring you can either install the Curt # C56110 if you have the rectangular OEM plug or the Curt # C55774 if you have the round OEM plug. Both of these options give you a 4-Way flat connector that will match up with your small utility trailer. Since pickups can be used for a variety of towing applications I highly recommend installing the B&W Tow & Stow 3-Ball Mount # BWTS10049B. This comes with the...

This is custom fit for your truck and will provide a 2 inch hitch opening with a 900 pound tongue weight capacity and 6,000 pound towing capacity. No drilling will be required during installation but the spare tire will need to be lowered or removed temporarily. I have attached an installation video on your vehicle for you to check out.

  • Troubleshooting Rear Parking Lights on 2011 Ford F-150
    The rear park lamp circuit in a 2015 Ford F-150 is protected by a 10A fuse in position 40, according to page 333 of the owner's manual. I suggest re-checking this one fuse position and trying a new fuse, just in case. It sounds like you have issues with both your F-150's own lighting functions as well as those on its trailer connector. This tends to suggest that the place to troubleshoot is the OEM wiring connection under the truck where items like 7-way # 118283 and 4-pole # C56110 plug...

    The parts necessary to provide a 7-way for your F150 would depend on how it was equipped when it left the factory. If your F-150 has the factory round plug located along the drivers side frame rail behind the back bumper, you would use part # 74682. The factory plug will have a dust cover that will need to be removed, and the 74682 would plug right it. If your F-150 does not have the round plug, but has a 4-pole connector, part # 37185 can be used. It would plug into the existing 4-pole,...

This kit has all the parts needed to upgrade the 4-pole setup to a fully functioning 7-way.
