• 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.

• 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...

• Brake Controller Installation on the 2009 Ford F-150 Without the Brake Controller Port

Once that is there then just add the Universal Installation Kit for Trailer Brake Controller part # ETBC7 which will give you a fully working 4 and 7-way trailer connector and the connections for your brake controller like the Tekonsha Prodigy P3 part # 90195 that you have.

• 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...

• Is there a Specific Wiring Color Code for a 7-Way Trailer Connector on a 2013 Ford F-150
  Factory wiring could be any color since there is no one standard that all manufacturers follow. You will need to test the wires by function using a circuit tester such as # PTW2992 if you do not already have one. I have included a picture that shows a standard 7-Way and how it is pinned out. That should help if you still have the wires attached to the factory connector.

• 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...

• Trailer Wiring Harness Recommendation for a 2013 Ford Edge
  It would appear as if the Replacement OEM Wiring Harness part # C56110 that you referenced would work on your 2013 Ford Edge since you have what looks like the correct port for it. By the way, thanks for the picture. What you can do to verify that the plug is active is use a circuit tester like our part # PTW2993 and test the different pins you see for voltage when the brakes/blinkers/running lights are on. If the pins carry voltage with the use of your taillight functions then the # C56110...

• What Hitch do You Recommend for My 2018 Ford F-150?
  If you do not have a factory hitch on your 2018 Ford F-150, I recommend the Curt Trailer Hitch Receiver - Custom Fit - 2" # C86HR. Not only does this hitch come with a 6,000 pound towing capacity and a 900 pound maximum tongue weight, it also comes with a superior gloss outer coating over the base coat that will provide more resistance against rust and corrosion that Draw-Tite and etrailer alternatives. Also, the installation includes a bolt-on process that only takes about 40 minutes to...

• 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...

• Wiring Harness For 2020 Ford F-150 Without Tow Package
  Where to start with your wiring harness depends on what available connectors you have under the bumper of your 2020 Ford F-150 and also what trailer connector you're looking to add on your truck.

• 4-Pole to 7-Way Wiring Conversion Kit for 2011 Ford F-150
  If your 2011 F-150 has a pre-installed 4-pole harness (which probably has a rectangular connector on the truck side like the one on parts # C56110 and # HM11140735; see the linked photo, please) then you can convert that wiring to a 7-way using kit # ETBC7.

• 7-Way Trailer Connector for 2011 Ford F-150
  The wiring harness you referenced, part # 118242 would not be compatible with your 2011 F150. It is designed for the 1997-2003 model years only. 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...

• Does Installing Curt 4-Way on 2017 Ford F-150 Require Flashing Computer at Dealer

• Recommended Towing Components For 2013 Ford F-150 For 2009 StarCraft Popup Camper
  I don't believe that the 2009 StarCraft Popup Campers needed to have trailer brakes, so for your 2013 Ford F-150 you will need a trailer hitch, 4-way wiring connector, and ball mount. Without knowing what you already have, I'll give you recommendations for each. For a trailer hitch receiver, I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" # 75691. This is an easy bolt on installation that will give you a 2 inch receiver opening. For a wiring...

• 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...

• Trailer Hitch, Wiring and Brake Controller Recommendation for 2014 Ford F-150
  First let's start with a hitch for your 2014 Ford F-150. For that the most popular option is the Curt # C14002 which I attached an install video for as well. You will need to start with a 4-way (if you do not have one). For that you would want the # 18252. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and...

• 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...
