Ask the Experts about this Hopkins Custom Fit Vehicle Wiring

Do you have a question about this Custom Fit Vehicle Wiring?


  • Why Do Some 7-way Plugs Use Dual Contact Surfaces
  • A 7-way (female) vehicle socket like # PK12-707E has a single blade contact; these fit in between the dual contact surfaces in a (male) trailer plug like # 54006-059, # 277-000143 or # A10-7W10 and the connector (type BB) shown in your photo. Some 7-way male plugs will use a single blade contact, such as the plug on Hopkins 7-way extension # HM20049. This item's female socket and male plug happen to both use the single contact. Both types are compatible with each other. The Bargman...

  • 7-Way Adapter Recommendation to Go From Semi Truck 7-Way to RV 7-Way
  • The part # PK12-724 is designed to plug into a 7-way round connector like what your semi-truck has and provide you with a 7-way blade type connector for your RV 7-way.

  • Making 7-Way Extension for Truck Towing Two Trailers
  • You'd have to install the # 41157 on your tow vehicle which comes with a 10 foot long 7-way socket extension that plugs inline with the 7-way you have at the rear of your vehicle. This could then be routed on the side of your trailer or underneath where you could use a 7-way extension like the # TLW6510 which is 10 feet in length. From there you'd be able to plug in the 7-way of your second vehicle.

  • 7-Way Extension for Towing Food Truck with 2003 Ford Expedition
  • Thanks for the picture of the trailer wiring connector you have. Based on that you are in need of a 7-way blade extension like the part # C56080 for a 7 foot long extension or part # HM20049 for an 8 foot long extension. Or if you are looking for something shorter you'd want the part # TLW6024 which is 24 inches long.

  • Converter to Separate Stop and Turn Signals on Trailer
  • I do not know what you are referring to by "semi-type wiring" but it sounds like you want to take combined trailer wiring circuits and separate the turn signals and brake lights. If so you will need the Vehicle to Vehicle Tail Light Converter # C56196 along with Diodes # 38955, which are going to help prevent power feedback.

  • How to Make an Adapter to Go from Semi Truck 7-Way Round to RV Style 7-Way Blade on Trailer
  • Either way is correct. It depends on if you want to keep the semi-style 7-Way (if you need to tow that type of trailer) or if you will never be towing a semi trailer. If you need to keep the 7-Way semi active on the truck then you would need to make an adapter to get it to work with an RV 7-Way. For that you would need a trailer side 7-Way round, # PK11702, a converter, # RM-732, and a vehicle side 7-Way RV style, # PK12-707E. A semi-7-Way has separate circuits for the brake lights...

  • Is there an Adapter to Go From Semi Style 7-Way to RV Style 7-Way Trailer Connector
  • Because the functions on a semi 7-Way connector are different than those in the RV industry a regular adapter would not work. Some of the circuits have to be combined so a converter is needed. It would actually be easier to just add an RV style 7-Way on the semi rather than making an adapter as described in the question you referenced. If your semi has combined brake lights and turn signals on the same circuits then you would just need a vehicle side 7-Way such as # 50-87-009 and wire...

  • Installing 4-Pole/7-Way Trailer Connector on Newmar Motorhome
  • There is not an off-the-shelf adapter that would convert your existing 7-way flat blade to a 7-way and 4-pole, but there are some fairly easy options for adding a 4-pole. You can access the wiring harness leading to the existing 7-way, and tap in a 4-pole harness like part # 18252, which would allow you to use both harnesses simultaneously. The connector includes a circuit tester which would help identify which circuit serves which lighting function. Another option would be to completely...

  • Adding a 7-Way Trailer Connector to the Bed of a 1997 Ford F-350 for a 5th Wheel Trailer
  • We do have the parts needed to add a 7-Way trailer connector to the bed of your 1997 Ford F-350. To determine exactly what you will need we have to first look at what type of trailer connector, if any, is on your truck. If it came with a factory installed 7-Way at the bumper check to see if you can unplug a round connector from the back of the 7-Way socket. There may be some locking tabs that you have to disengage to disconnect it. If it is set up that way and the connector is round...

  • Tow Bar Lighting Recommendation for a 2001 Honda Accord
  • For tow bar wiring for your 2001 Honda Accord that will allow you to control the taillights of the vehicle you would want the part # RM-152. You will also want the # BX88206 to connect this lighting solution to your tow vehicle. This comes with a round 6-way connector that you will install on the front of your towed vehicle and enough coiled wire to go from there to the tow vehicle.
