Expert Answers about Ford Wiring


  • Can 5-Way Trailer Connector Circuit Tester be Left Plugged In While Driving
  • Yes, you can leave the tester, # 20115, plugged in while traveling. It is not going to fall out, especially when you are towing a trailer since it would be sandwiched in between the vehicle side connector and the trailer connector. But you might find that leaving it in place is not the best idea because you are essentially adding another link in the connection between the trailer and the vehicle.

  • Only Right Turn Signal Works on Tow Package Wiring on a 2001 Ford Ranger
  • If the wiring harness on your 2001 Ford Ranger is a factory installed harness then there is likely fuses or even relays related to it. The best way to find them is to consult the owners manual for the truck. None of the aftermarket harnesses for the truck have fuses. It could still be a ground issue on the truck. Just make sure that the main ground from the harness is attached to a bare metal surface, no rust or paint. Move the ground if you need to. If you cannot access the truck wiring and

  • Will the Curt Trailer Connector # C57101 fit the Factory Harness of a 2012 F350
  • Unless someone changed the wiring of the factory 7-way on your 2012 Ford F350 then it should be wired like the picture I attached. I think you might be referring to the release tab on the factory harness for your 7-way. Which if you check out the picture I attached you will see the back of the Curt Trailer Connector part # C57101 and you will see that the release tab attachment point is in the 1:00 position from the view of the picture, but if you were installing it in your harness it would m

  • Continual 12V Power on at the Trailer Connection of a 2001 Ford F350
  • In order to have a 12V power supply at the vehicle connection point for a trailer you will need to have a fully functioning 7-way. For your truck I recommend using the Tow-Ready Custom Fit Vehicle Wiring Harness # 118243. This harness will replace your existing 4-way, and upgrades it to a 7-way connection using the factor plug. The fuses and relays are included that will be used in your power distribution box, and the trailer towing relay block. Once you have a functioning 7-way installe

  • Installing a 4 and 7-Way Trailer Connector on a 1999 Ford Van Cut Away RV
  • We have a help article that explains how you would go about installing a 7-Way trailer connector on a Ford full size van, or in this case an RV cutaway built on the van chassis. It very well could be different on the cut away models but there are no custom fit options made specifically for the cut away models. If the van did not come with a factory installed 7 or 4-Way connector then you will have to start by hardwiring in a 4-Way using T-connector # 118344. Then to install a 7-Way you will

  • Trailer Running Lights Not Working When Connected to 4-Pole Harness # 18252 on 2007 Ford F-150
  • The first step for troubleshooting your 4-pole installation is to check that the lighting functions on the vehicle itself are operating correctly. This needs to be checked first since the part you referenced, Draw-Tite 4-Pole Hardwire Kit # 18252, relies on input signals from the vehicle lights to send output signals to the trailer. If the vehicle lights are not working properly you will need to get those fixed first. Once you have confirmed the vehicle light functions are all okay you can move

  • 12 Volt Circuit Not Working on a 2002 Ford Expedition
  • The easiest way to check a relay is to use a known good relay in place of a potential bad one. Then if the circuit starts working again you know that was the problem. Also there could be additional fuses that are not obvious but that are associated with the tow package wiring. The best place to ensure you have found them all is the owners manual. If you cannot find any other fuses and the relays are all good then you can bypass the factory wiring. You will need about 20 feet of wire # 10-1-1
