Expert Answers about Ford Wiring


  • 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...

  • 7-Way Wiring Harness for 2008 Ford F-150
  • The 7-way wiring harness kits offered for your 2008 Ford F-150 are shown on the linked page and all include both the wiring harness portion and the trailer connector as well, such as PK11893-11932 from Pollak and Tow Ready # 20119. Both of these use a standard round U.S. Car connector. The part you referenced, # 118247, uses two OEM connectors and is a fit for 2004 model year trucks but not for your 2008 F-150.

  • Replacement 7-Way Trailer Connector and Wiring Pigtail for 2013 Ford F150
  • I'm not sure what you mean by harness clips, but the # HM40975 will work as a replacement for the existing 7-way on your 2013 Ford F150. If the US car connector that plugged into the back of your existing 7-way has been damaged, then you can cut off the existing US car connector and wire on the # PK11998 pigtail. The pigtail wires are color coded as follows: Red - Left Turn and Stop - 14 gauge White - Ground - 10 gauge Blue - Electric Brakes - 12 gauge Green - Right Turn and Stop...

  • Adding a 7-Way Trailer Connector and Brake Controller to a 2005 Ford E-150 Van with 4-Way
  • I have seen 4, 5, 6, 7, 9, 12, and 13 pin trailer connectors but never an 8 pin connector. Are you sure it is an 8 pin and not the regular blade style 7-Way such as # H20044? If it does not look like this please send me a picture of the trailer's connector so I can determine what it is. If it is indeed a regular RV style 7-Way then we do have the parts to add a mating 7-Way to your 2005 Ford E-150 van. You will need # ETBC7 to add the 7-Way, retain the 4-Way, and have the wiring needed...

  • Converting Wiring On 1998 Ford Ranger From 4-way To 7-Way For Trailer
  • We have what you need to convert your wiring from 4-way to 7-way to match your trailer. You can cut the round connector off on the vehicle side and replace it with part # HM48035. Then you need to use part # ETBC7. Your 4-way flat will plug into the # ETBC7 and you will need to run the additional wires. You will need to attach the white wire from the # ETBC7 to a clean bare metal surface for a ground. The blue wire will go to your brake controller. The purple wire is used for reverse...

  • Can Wire Torn from Factory Wiring Connector be Reinstalled on 2006 Ford Expedtion
  • It sounds like the blue wire on the factory connector tore off of the round connector that plugs into the back of the 7-Way trailer connector. I have a solution for you, but unfortunately we do not know of any way to install a new wire into the factory connector. The best solution I have for you is to cut off the existing round connector and install a replacement harness and connector, # PK11998. This replacement connector will need to be connected to the existing wires on your 2006...

  • 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.

  • Electric Trailer Brakes Not Working on 2002 Ford Excursion but Work w/2003 Ram with Same Controller
  • It is possible that on your 2002 Ford Excursion the output wire (blue on the controller) is not connected to the trailer connector at the back. You can test this by testing the 7-Way pin in the 5 o'clock position with a circuit tester such as # 3808 or a meter while someone sits in the vehicle and fully applies the manual override. If no power shows on that brake output pin then the likely cause is that the connection is not complete from the controller to trailer connector. This could...

  • Trailer Wiring Harness for a 2007 Ford F-150
  • It sounds like that 2-pin connector you found might be related to power lights or a brake light in/on a camper shell. If it is not that then I am not sure what it would be for but I can tell you that it will not be for trailer wiring. To add a 4-Way on your 2007 Ford F-150 you can use # C56031. I have included a link to a video review of this harness for you.

  • P3 Brake Control Shows No Trailer Connected Even with Trailer Connected to 2002 Ford F-150
  • A brake controller like the P3 # 90195 senses the brake magnets on the trailer when connected to the truck. It is possible that the blue wire (brake output wire from the controller to the trailer) is broken or missing somewhere so it cannot sense the trailer. To test this adjust the controller to the highest setting. Then have someone sit in the truck cab and fully apply the manual override lever while you test the brake output pin in the 7-Way connector at the back of the truck using...

  • Can Hopkins Multi-Tow Trailer Connector Adapter HM47675 Deliver Lights and 12V Power Simultaneously
  • The 12V power circuit on a 7-way trailer connector is separate from the lighting circuits. If you use an adapter like the Hopkins Multi-Tow Trailer Connector Adapter # HM47675 the 4-and-5-pole connector will carry the stop/turn/tail light signals for the trailer lights while the 12V power outlet will deliver a maintenance-level charge to keep a charged battery topped off. Both will operate at the same time. Do note that this 12V power feed, which comes through your F-150's trailer wiring,...

  • Solution for Trailer Wiring Harness on a 2008 Ford F-150 With Dead CIRCUIT at Fuse Slots
  • If there isn't power to either side of the fuse slots on your truck when the blinker is on that is not a great sign. That would indicate a much larger problem upstream of the fuse box. To save yourself the headache, you might just bypass the factory 4-way by installing a part # 18252 which would just hardwire to your truck's wiring.

  • Adding a Functional 7-Way with Reverse Light Circuit to a 2004 Ford F-150
  • If your 2004 Ford F-150 has a factory installed 4-Way trailer connector and you install 7-Way # 118247 and its relay (and all of the other tow package fuses/relays are in place) then you will have a fully functional 7-Way connector and the reverse light circuit will be active. This will then activate the reverse lockout solenoid that is on the boat trailer so the brakes won't engage when in reverse.

  • Parts Needed to Install a Brake Controller in a 1999 Ford Expedition with 4-Way
  • One of the components needed to install a brake controller in your 1999 Ford Expedition is the part # 37185 that you referenced. You would also need a brake controller and install harness. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies...

  • Connecting Wires of 37175 4-Pole to 6-Way Adapter to Install Brake Controller on 2011 Ford F150
  • The # 4 pole on the 37175 would plug directly into the existing 4 pole on your truck, leaving three remaining wires. The blue wire carries the output voltage from the brake controller, the red wire carries 12-volt auxiliary power from the vehicle to the trailer and the white wire is a ground. The red and blue wires would be lengthened and ran under the vehicle up to the engine compartment. The blue wire would run through the firewall and connect to the blue wire exiting the rear of the...

Signal wires, like yellow, green, red, and brown, draw less amperage so they use a lighter gauge wire. Heavier gauge wire is used for functions like the brake signal, ground, and 12V power because they carry...

  • Troubleshooting Wiring On 2014 Ford F-150 When Backup Camera Is Not Working
  • It sounds like you have a wiring issue on your truck somewhere. Since you said you are getting very little current when you test the reverse pin on your 7-way connector that would be where you want to start. Use a circuit tester like part # 3808 to check the power going into the 7-way connector on the truck side. If it still reads very little as you said then it is further upstream in the wiring. It could also be a ground that is loose. Look for signs of corrosion or a pinched or broken...

  • Trailer Wiring Recommendation for a 2004 Ford Crown Victoria

Ford might offer a harness that would allow you to plug in further up the truck bed, but the best bet we offer would be # PK11998 pigtail or if you're also missing the trailer connector, part # HM40975-11998. The pigtail would need to be connected to the cut wiring, so I'd recommend using a circuit tester like part # 40376 to determine which wire carries which circuit. Have a helper activate...

  • Recommended 7-Way for 2012 Ford F-150 XLT Without Factory Tow Package
  • The Bargman 5th Wheel and Gooseneck 90-Degree 7-Way Pigtail Harness # 51-97-407 is a general-purpose wiring harness kit that is not vehicle-specific. This is intended for hardwired installation to the vehicle's existing wiring using the pigtail leads. Do note that the function carried on each wire is noted in the products specs. Matching wire functions is the best way to install a harness since wire colors are not 100-percent standardized. If you do not have any tow wiring on the truck...

  • Troubleshooting 4-Way Flat Factory Connector Only Testing for Power on Turn Signals
  • Since you have a factory tow package wiring, I recommend checking the tow package fuses to be sure none of the fuses are blown. If the fuses are fine, next you will want to check the wiring behind the bumper for any damage. There may be a short from a cut or pinched wire that is causing problems with the 4-Way connector. Next you can test the functions of the 4-Way with the tester grounded on the ground pin of the connector. Using the 4-Way connector's ground will ensure that the...

  • Video of Converting Trailer Wiring 4-Way to 7-Way for Ford F-150
  • I think I found the video you are referring to and attached it to this page. Basically it shows how to convert the 4-way of a 2013 Ford F-150 to a 7-way and activate the 12 volt power circuit. The adapter used in the video is part # 37185. Other parts used in the video: # 10-1-1 10 gauge wire sold by the foot # 05732-2 for butt end connectors # 459075-1 for wire loom # 11755 for dialectic grease # 7012A for 30 amp breaker

  • 7-Way Trailer Wiring Connector Recommendation for a 1999 Ford F-250 with Factory 4-Way
  • To wire in the # HM40975-11998 would require a couple fuses and relays. Your best option is going to be to get the # 118243 instead as it comes with the fuses and relays needed. It also has a square connector that will mate right up to the trailer wiring connector you have on your truck already. Trying to install the harness you have would be quite a headache. I would strongly recommend you get the part # 118243. I attached an install video for this harness for you to check out as well.

  • Trailer Wiring Recommendation for a 2004 Ford Escape without Tow Package
  • For your 2004 Ford Escape you would actually need a powered trailer wiring harness like the part # 46255 that uses the power from the vehicle battery to power the trailer taillights instead of the taillight circuits of the vehicle for the trailer taillights like the # 119178 does. A powered harness will have a wire that runs up to the vehicle battery and then uses the wires run to the vehicle taillights as signal wires. If you use the # 119178 on your vehicle you may end up shorting...

  • Should an Electric Trailer Jack Run Off of a Trailer Breakaway Battery
  • The trailer jack should very much NOT be powered by the breakaway battery. That was likely done by the previous owner for convenience. 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. Most breakaway...

You want to make sure your connector is wired the same as the attached photo of a 7-way connector. If not, then you want to change the wiring and place the wires in the right order. You can also check to see if any of the wires are touching each other inside the 7-Way. Check for corrosion or dirt and clean it up as that can cause shorts...

  • Using a Switch and Trailer Mounted Battery to Power Interior Trailer Lights
  • What I recommend is to wire up the lights via a switch installed inside the trailer and connected to the battery. You can mount the battery where needed but 10 gauge wire will be too large for lights. A lot depends on the lights and how much power they draw but 16 gauge wire such as # 16-1-1, sold by the foot, would likely be all you need. For a switch you could use something like # PK34513. It is a basic on/off toggle switch rated for 10 amps. Another option is # PK33300 rated for...

So it is not unusual that the tester you are using showed power on the turn signal indicators when the brake pedal was pressed on your 2004 Ford F-150. They should also come on when the turn signals are used. Assuming that all the functions work on the truck side, the problem must be on the trailer side. It could be...
