Expert Answers about Ford Wiring


  • Installing 7-Way on 2013 Ford Explorer Towing Pop-up Camper with Surge Brakes and Electric Lockout
  • If the trailer plugs into a 7-Way then you can use # 30717 and you would just have to ground the white wire and splice the yellow wire into a reverse light wire on your 2013 Ford Explorer. The black wire is for 12 volt power (if the trailer uses 12 volt power) and will need to be run to the vehicle battery via a 40 amp circuit breaker # PK54540 and about 25 feet of wire # 12-1-1 which is sold by the foot. The blue wire you can tape up and stow out of the way. The # ETBC7 kit comes...

  • Trailer Connector Adapter to Power Reverse Lock Out on Trailer with Hydraulic Surge Brakes
  • It sounds like you have a 4-way trailer connector on your 2015 Ford F-350 and a 5-way connector on the 2010 GMC. The fifth pin on the 5-way connects to the truck's reverse light circuit and tells the trailer's reverse lock out to prevent the brakes from locking up. If the Ford only has a 4-way connector it's missing this feature. You can use an adapter like the Hopkins # 47515 on the Ford and connect the extra wire to its reverse light circuit to power the fifth pin. If the Ford...

  • 7-Way Adapter Recommendation for 1997 Ford F-150 with 4-Way
  • What you are in need of is the part # 37185. This plugs into the 4-way of your truck and gives you both a 7-way and a 4-way for your trailer to attach to. It also can be used for if you wanted to add electric brakes to your trailer in the future, but if not needed you just simply would need to tape up the extra wires as they wouldn't be needed.

  • Is the Hopkins Adapter 4-Pole to 7-Pole and 4-Pole a Solid Piece or Can it be Taken Apart
  • You can most certainly disconnect the wiring at the rear of the Adapter 4-Pole to 7-Pole and 4-Pole # 37185. This 4-Pole to 7-Pole and 4-Pole adapter can also be found in our Universal Installation Kit # ETBC7 along with the additional wiring and other parts needed to add a 7-Pole (or 7-Way) connector to your 2016 Ford F-150 if it just has the 4-Pole. I have attached videos of both of these products being installed on two similar 2013 F-150s.

  • How To Troubleshoot A Brake Controller That Recently Stopped Working
  • If your brake controller was previously working and just began to stop, their are a few things you will need to test. The first thing you will need to check is that the brake output signal is reaching the 7-way on the back of the vehicle. You can do this by attaching a circuit tester such as the Quickee Circuit Tester part # 3808 to the blue wire and activating the manual override on the brake controller. If the wire is receiving power then the connection is bad on the trailer side....

  • How to Determine Wire Functions of Trailer 7-Way with only 4-Way Wiring Ran for Installing 7-Way
  • Sounds like your trailer uses a 7-way connector but only has taillight functions carried on the connector so that is why you only have the 4 wires ran to it. What you need to do is determine what each of the wires carries by either tracing the wiring back to the lights or by putting 12 volts on each wire of the circuits with a car battery jumper wire to determine which wires activate each circuit. Then use the attached diagram to wire it accordingly.

  • Troubleshooting 7-Way Socket on 2006 F-150 Used with 7-Way-to-4-Pole Adapter
  • It is best to first test the 7-way on your F-150 without the 7-to-4 adapter plugged in. You will need a circuit tester like # 3808 or # 40376 to test the pin for each lighting circuit on the 7-way. Please refer to the photo I linked for you that shows what signals are to be found on each pin of a 7-way vehicle socket like # 37185. Testing this first lets you know the right signals are there for the adapter. In a 7-way type socket the running light signal for both sides of the trailer...

  • Trailer Wiring Harness Recommendation for a 2011 Ford Escape
  • Technically you could use Hopkins trailer wiring harness # HM48915 on your 2011 Ford Escape. But since your 2011 Ford Escape uses a combined wiring system (brake lights and turn signals on the same bulbs) you would ground the red wire with the white wire. Brown is for running lights, yellow is left turn/brake lights, green is right turn/brake lights, and white is ground. Using this harness means you would have to splice into the vehicle wiring. For a much easier installation I recommend...

  • Troubleshooting No Trailer Lights on Tilt Bed Utility Trailer with 2002 Ford F-250 Super Duty
  • Tilt trailers can sometimes create grounding issues because of how the bed attaches to the frame. Since the ball mount seems to be making a difference that also makes me think it's a ground problem since sometimes on trailers with bad ground harnesses they can still ground through the hitch if available. What you will want to do is try running a jumper ground wire from the lights back to the ground circuit of the trailer harness. I can almost guarantee that's going to fix the problem.

  • The trailer connector I recommend is part # 37185. This connector can be installed with your existing 4-way connector, or you can remove the 4-way connector and hardwire the adapter that will give you a working 7-way and 4-way trailer connector. I have attached a link to a helpful article about trailer wiring you can check out.

  • 7-Way Adapter Recommendation for Adding 7-Way to the Bed of a Truck
  • Yes, what you need is a fifth wheel/gooseneck 7-way setup like the # 41157. This kit installs in line with the 7-way at the rear of your truck and gives you a second one to install in the bed. You will have to swap out the # 37185 and use a # HM47200 since it allows the connector to separate behind the 7-way.

  • Troubleshooting Brake Controller in 2008 Ford F-250 Gas Pickup
  • There are many reasons why a trailer brake controller could fail to operate. Since I do not know anything about your controller or its installation I can give you some general guidance. If the controller does not light up (if it appears not to have power) then start by testing the black wire that delivers 12V power to the unit. Use a circuit tester like # 40376 or # 3808. If you do not get a signal on the black wire then check your fuse/circuit breaker. You should have 12V power on that...

  • Adding a 5-Way Trailer Connector to a 2008 Ford Super Duty and Trailer for Reverse Lights
  • If your 2008 Ford Super Duty came with the factory installed 7-Way trailer connector then all you would need for it is a 7- to 5-Way adapter # A75TB. If your truck came with the factory 4-Way then you would need adapter # 20036 and the blue wire will splice into a reverse light wire on the truck. Then for the trailer you can install a 5-Way wiring harness # HM47910. The existing light wires can splice to this harness but for reverse lights you would need to add wire, # 16-1-1 sold by...

  • How to Tow a Trailer that has a 5-Way Trailer Connector with 1984 Ford F-250 that has a 4-Way
  • Since your 1984 Ford F-250 already has as 4-way flat trailer connector all you need for the connector is an adapter # 47515. Your existing 4-way will plug into the adapter and the additional blue wire will need to be tapped into the truck's reverse light circuit using the included quick splice wire connector. I've linked a video of the adapter being installed onto a Nissan Murano. The vehicle is completely different but the process is still the same.

  • How to Prevent a 12 Volt Power Circuit on a 7-Way from Being Active All the Time
  • What most people use to allow the 12 volt charge wire from being hot all the time and only when the key or the vehicle is on is an isolation solenoid part # TR118665 on the charge wire. You basically run the center pin to a keyed power source and then run one side of the solenoid to the 7-way and the other to the wiring of the truck. If you were wanting to install it on a 4-pole connector that was used strictly for that circuit that is possible too. This wouldn't work through a 7-way...

  • 12 Volt and Reverse Light Circuits Not Working on 1999 Ford F-250 Tow Package
  • There are also relays associated with the reverse light and 12 volt circuits for the tow package wiring on a 1999 Ford F-250. There are also multiple fuses for each. If any one of them is bad or missing then that circuit will not work. The relays are in locations 38 and 39 in the fuse panel so those are the first to check. There are also a fuses in locations 4 and 16 in the under hood panel and in location 28 in the in-cab fuse panel.

I reached out to my contact at Cequent and the T-One # 118384 should fit without issue if you want the second 4 way in line. The only reason why the male end may not connect properly is if there is a bent pin on the male side or something stuck in the female side of that...

  • Trailer Running Light Pin on 2013 Ford F-150 Trailer Connector has No Power
  • It could be a tow package fuse or relay that is causing the trailer running light circuit to fail on your 2013 Ford F-150. In the power distribution box the fuse that feeds the trailer park lamp relay is in position 6. Also check position 67. I am almost certain that it is a fuse/relay that needs to be replaced but if not then like you said this is an issue somewhere in the wiring that will need to be tracked down.

  • How to Troubleshoot the Voltage From a Brake Controller on a 2005 Ford F-250 and F-350 Super Duty
  • If you have the controller set to max gain then you should be getting 12 volts. Instead of a voltage tester I strongly recommend using a circuit tester with an incandescent bulb like part # 40376. The bulb will basically trick your brake controller into thinking that there is a trailer connected to it by placing a load on the circuit where a voltage meter does not. Some brake controllers will not send back full voltage if they don't sense a trailer is connected. If you are using...

We do offer universal wiring harnesses that will work for you but you will need to identify the wires for each of the functions by using a circuit tester like part # 3808. You will need to first install a 4-way harness like part # HM48030. You will also need a 7-way connector for the RV so I recommend part # ETBC7. This plugs...

  • Troubleshooting Trailer Wiring that Stops Working When Headlights Are On

Or you can run all of the trailer wires back to the main ground. This is actually the ideal solution. But you can also check the current grounds for the lights to make sure they are making a solid connection to a clean metal surface. What you described is the classic insufficient ground scenario so finding a way to improve the grounds will fix the problem.
