Expert Answers about Ford Wiring


  • Can a Non-Powered Trailer Wiring Harness be Used on a 2014 Ford Escape
  • I wouldn't say you are completely wrong. The reason that some vehicles require (or it is recommended) a powered trailer wiring harness is because modern vehicle wiring has become so then that it often times cannot handle the additional power draw from trailer lights. In other circumstances if the vehicle computer sense more draw than what its own lights draw it can cause error messages and might not allow the trailer lights to work. A powered trailer wiring harness supplies the power...

  • Compatibility of Hopkins 4-Pole to 7-Pole Adapter 37185 with Wiring on 2005 Ford F-150
  • The Hopkins 4-Pole to 7-Pole Adapter # 37185 and the similar Tow Ready part # 30717 are not vehicle specific products. Either can be installed on any vehicle that has a 4-pole already in place. Between the two I recommend the Hopkins since it allows you to have both connector types in place at one time and it includes a mounting bracket. The Tow Ready gives you only the 7-way and no bracket. Please refer to the linked photo that shows you how to connect the four pigtail leads for...

  • Ring Terminal Sizes Needed for Installing Epicord 7-Way Plug with Junction Box 277-000141
  • The terminal posts in the Epicord 7-Way Molded Trailer Plug with Junction Box # 277-000141 are indeed a 3/16-inch diameter. You can use ring terminal # 44-5310A for connecting 10- and 12-gauge wires. For the lighter 14-gauge wiring use part # DW05702-1. You'll need a crimping tool like the one included in our Deluxe Trailer Wiring Kit # HM51020. I also recommend using dielectric grease # 11755 on those connections to protect them from moisture and corrosion.

  • Best Way To Check Brake Light Signal For An Electric Brake Controller On A 1997 Ford Explorer
  • When checking the wires associated with a brake controller, you should use a incandescent circuit tester like the Quickee Circuit Tester # 3808. This will actually cause a power draw on the wire to light the bulb and give you an accurate visual of if the system is functioning correctly. You will need a 12V power for the brake controller to work. I can confirm you are testing the correct wires and that the green wire will connect to the red wire on your brake controller. If the incandescent...

  • Recommended 4-Way To 7-Way Adapter For 2008 Ford F-150 With 4-Way Trailer Connector
  • We do have a wiring adapter that will plug into the 4-way on your 2008 F-150 and give you a 7-way and a 4-way at the back of your truck. You will need part # 37185. This gives you the 4-way functions and the additional wires for the 7-way are available for brakes, power, and an auxiliary wire for 12V power, reverse lights, or even a reverse lockout for trailer brakes. The black wire is for 12V power from the positive post on the battery. The white wire is a ground and is attached to...

  • Adding a 7-Way and Brake Controller to a 2015 Ford Expedition with Factory 4-Way
  • From what we have found the 2015 Ford Expedition that came with a factory 4-Way connector will need a little bit of hardwiring to install a brake controller and 7-Way connector. You will need # 37185, some wire (more on that later), a brake controller, and a brake controller wiring harness. The 37185 will plug into the 4-Way. Then you will ground the white wire to the frame. That will leave a blue wire, black wire, and purple wire. The purple wire is for reverse lights so if the trailer...

  • Troubleshooting Light Bar Installation On 2015 Ford F-150
  • It sounds like your light bar has been wired incorrectly. You somehow tied the light bar wiring into the wiring that identifies a trailer. I recommend disconnecting the wiring for the light bar. Most have just two wires. One is typically white with a ring terminal and that is the ground which should be attached to a clean metal surface. The other wire should be attached to a wire that shows power only when the running lights on your truck are on. You can use a circuit tester like...

  • Parts Needed to Convert 4-Pole Harness to 7-Way on 2012 Ford Escape
  • You can convert your Escape's 4-pole trailer wiring to a 7-way that includes a 12V power feed to help maintain your trailer-mounted battery. You will need part # 37185. This item simply plugs in to your existing 4-pole. All you'll need then do is connect the ground wire and run 10-gauge wire # 10-1-1 from the battery + post through a circuit breaker # PK54540 and back to the 7-way where it will connect to the black wire on # 37185. A wiring kit like # HM51020 includes the ring terminals...

  • Troubleshooting Trailer Taillights that Stop Working When Headlights are On
  • Your main problem is an insufficient ground for the trailer wiring. Try improving the connection of the main ground wire of the trailer wiring harness. Make sure it is attached to a clean metal surface. 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...

  • Can a Trailer Battery Get Charged by a 12 Volt Accessory Circuit from a 7-Way
  • Yes, what you are interested in doing is something that is very common for people who have powered jacks on their trailer. You should note that a wire ran from the 12 volt circuit of the 7-way will only put a maintenance charge on the battery and would not charge a dead battery. But if the battery has a good charge on you will be able to keep the battery going for as long as possible between charges with this method. You would want to run 10 gauge wire from the 7-way to the battery like...

  • Trailer lights
  • It sounds like there is either fuses or relays blown on the truck or the trailer connector on the truck side has corrosion in or on it. Checking the fuses and relays is easy. Just locate the tow package fuses/relays using the owner's manual or the legends on the fuse panel lids (many vehicles have fuse panels in the cab as well). For a relay the easiest way to check for a bad one is to use a known good one in its place. Inspect the trailer connector and make sure it is clean and free...

  • Recommended Wiring When Adding 7-Way Trailer Connector To 2016 Ford Escape
  • First, I would recommend using part # 37185 instead of the # C57674 you mentioned because the test lamps on the connector can cause issues with the Tekonsha Prodigy RF Wireless Trailer Brake Controller, part # 90250. The best way to run the system is to connect the black wire from the # 37185 directly to the positive battery post for your 12V power on the 7-way. This prevents any issues with power draw and possibly performance problems with the lights on the trailer. I have attached...

  • 7-way trailer connectors can be wired in several ways and heavy-duty commercial/agricultural round-pin 7-way wiring can be different too. Please refer to the linked image to see the different vehicle-side connectors and their common wiring configurations. To use your trailers that have plugs like # PK11702 with your F-250 you will need to install a socket such as # PK11720. A circuit tester like # 3808 will help you identify the function on each wire of the truck's existing 7-way. The...

  • 7-Way Wiring Harness Recommendation for 2015 Ford F-150 with 4-Way
  • 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 # 22292 and the # 37185 and a brake controller. 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 but the # 22292 plugs in under the dash of your truck. For a brake controller I would recommend the Prodigy P2 Brake Controller...

  • Recommended 7-Pole Round Plug & Play Wiring Harness Adapter for 2005 Ford Super Duty Factory Wiring
  • It sounds like your 2005 Ford Super Duty was outfitted with the 7-way blade system which is the most common in the market today. To adapt your 7-way blade to a 7-pole round for your trailer, I recommend the Pollack # PK12728. This 7-pole connector is prewired to simply plug into your truck's 7-way plug. It has the # PK11720 connector you referenced but is pre-wired like you are desiring. A great mounting bracket for the # PK12728 is the # PK11771. I have linked all the above...

  • How to Get Blue Brake Output Wire to 7-Way on a 2015 Ford F-150 with Factory 4-Way Connector
  • On a 2015 Ford F-150 that has the factory 4-Way flat connector you can either cut the blue wire back from the brake controller and run a wire from it to the blue wire on the # 37185 adapter like you said or access the wire were it terminates further back under the truck. I recommend the second method because it is less work and you can still just plug in the brake controller using harness # 22292 (for Tekonsha controllers) or the specific harness to match the brake controller you have. Both...

  • Is the 12 Volt Hot Lead Required when Installing a 7-Way Trailer Connector
  • Trailers that use 12 volt power for accessories or that have a battery will use the 12 volt circuit in a 7-Way trailer connector. If the trailer does not have those items then you would not have to make that circuit active. That means that you would not have to run any wire or install a fuse or relay associated with the 12 volt circuit.

  • No Power to Trailer Brakes when Connected to 2003 Ford F-350
  • The blue wire on a brake controller is output to the trailer brakes. If that wire is not connected the trailer brakes will not be getting any power. If there is a break in that wire somewhere between the controller and the trailer connector then that could be why it isn't working when the wire is connected. You could bypass it by running your own wire if you wanted to. The ABS system should be separate from the wiring for the brake controller. Usually the only time the ABS comes into...

  • Is Using a Brake Controller Necessary for Towing a Trailer
  • If the trailer is equipped with electric brakes and you want them to actuate, you'll need a brake controller. A brake controller is a fairly small investment that will go a long way to keep you safer when towing. There are two types of controllers, the older time-delayed variety and the newer proportional type. I'd recommend going with a proportional controller like the Tekonsha Primus, part # TK90160. A proportional controller can sense how quickly the tow vehicle is braking, and...

  • Where Does Fifth Pin of Trailer 5-Way Run to Activate Reverse Lock Out Solenoid
  • Sounds like you are trying to activate a reverse lock out solenoid on a surge brake trailer so that it can back up freely. The fifth pin that is the furthest from the jacketed ground pin is the fifth circuit to use. This circuit would need to tap into the reverse light circuit of your tow vehicle. I attached an install video for the 5-way adapter part # 47515 that shows this process on a 2014 GMC Acadia.

The Ranger does not have a port available under the dash with the functions needed for the brake controller pre-ran. You will want to hardware the installation of the brake controller....

  • Trailer Hitch and Wiring Recommendation for a 2001 Ford F-250 Stake Pocket Truck
  • If there is no trailer wiring at all at the rear of your 2001 Ford F-350 with a stake bed you are going to have to hardwire in a 4-way and then a 7-way adapter after. If there is a 4-way connector currently or you find the square connector that the part # 20031 attaches to you could go that route as well. For a hardwire 4-way you would need the part # 18252. Now 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....

  • Recommended Parts for Re-Wiring 5-Pole Flat Boat Trailer to Match Truck 7-Way Wiring
  • Adapters like # 37385 and # HM47570 are convenient and can work fine for the short-term but for long-term reliability you are really better off replacing the connector on the trailer to a 7-way that matches your truck with no adapters - or their potential problems. Those extra connections can mean more chances for corrosion. You can easily test your truck's 7-way using a circuit tester like # 40376 or # 3808. Have a helper activate each function while you apply the tester to the appropriate...

  • 4-Way on 2005 Ford F-150 4- and 7-Way Connector Not Working But 7-Way Is
  • If the 7-Way is working on your 2005 Ford F-150 then using adapter # 47345 will work as well. Usually a 7- and 4-Way combination connector uses the same wiring for both the 4- and 7-Way receptacles so it is odd that the 4-Way is not working but the 7-Way is. It could just need to be cleaned or the wiring connections re-established to start functioning again.

Unfortunately, unless you can locate the OEM 7-way that would have the 6 pin plug on the other end, you'll need to do some splicing. If the connector you found is active, to splice in a 7-way I'd recommend the Hopkins # HM40975-11998. The pigtail included with the connector uses a different wire color code that usual, see the bottom of the...

  • Parts Needed to Flat Tow a 2016 Ford F-150 King Ranch with LED Tail Lights Behind an RV
  • For tow bar wiring for your 2016 Ford F-150 I recommend going with a wireless kit # NV-5164. The issue is that the diode kits and converters that go with them are not rated for use with LED tail lights. The best option then is going to be a magnetic kit. And having a wireless system means you won't have to run any wires or worry about complicated installations on the truck. Since the lights are magnetic you may need to use tow light partners # TLP01 in the windows of the truck if the...

Look for a small solenoid located at the rear of the actuator with a wire tied into the trailer connector. Since your F150 has the factory tow package, the center pin of the 7-way should be tied in with the reverse light circuit. You can test this by using a circuit tester like # 40376 on the 7-way. The center pin should power up when...

  • Should an Electric Trailer Jack Run Off of a Trailer Breakaway Battery

The breakaway battery is a dedicated battery for the breakaway system only. It needs to be able to apply the trailer brakes on full for 15 minutes. If the jack was to run down the battery then the breakaway system would not be able to power the brakes for long enough. Also, a breakaway battery is too small for the power needs of a jack.
