Features:

  • Heavy-duty, coiled cable
    • Weatherproof jacketing
  • Easy-grip, translucent Nite Glow connectors
    • Light up when connected to confirm continuity
    • Assist with hookup in the dark
  • Tin-plated terminals for corrosion resistance


Specs:

  • 3' Cable when stretched
  • 7 RV blade (on vehicle) to 5-wire flat (on trailer) connector
    • Carries the brake, turns, tail, reverse and ground functions from the vehicle


Flex Coil Adapters provide increased durability and the additional length that may be necessary to reach between the tow vehicle's socket and the trailer/towed vehicle's plug.

In addition, Flex-Coil Adapters with Nite Glow illuminate on activation of the tail light function. This enables the user to find the electrical connection in the dark and shows that the vehicle's trailer wiring system is working properly.

Great item, I first had the four pin model which is also great. Had to get 5 pin model for boat trailer that has surge brakes. 78001

This item is extremely well constructed you will not have any issues with it. It is nice that it lights up at night to let you know that is connected correctly.

  • How Many Trailer Brakes Should be Used with a 20 Amp Circuit Breaker or 30 Amp Circuit Breaker
  • The recommendation for 2 to 4 brakes is a 20 amp circuit breaker, # PK54520, and for 6 to 8 brakes a 30 amp circuit breaker, # 38630, just as you have stated. Usually, you would go with the smallest sized circuit breaker for the system being used. This is so if there is a problem, it can be caught right away. If you plan on towing trailers with 2 to 4 brakes and trailers with 6 to 8 brakes, it would be best to go with the 30 amp circuit breaker as the 20 amp circuit breaker would not...

  • Is Hopkins Coiled Adapter 7-Way To 5-Way And 4-Way Flat, # HM47025, Available In 5 Foot Length
  • The Hopkins Heavy-Duty Trailer Coiled Wire Adapter 7-Way to 5-Way and 4-Way Flat, # HM47025, is only available in a 3 feet length. I have the RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit, # RM-146-7, that is 8 feet long, but you would need to remove the 6-pole plug and attach the Draw-Tite 5-Flat Vehicle End Harness, # 20016, to give you a 5-Flat vehicle end or the Tow Ready 4-Flat Vehicle End Harness, # 18002, to give you a 4-Flat vehicle end. The wires on the 5 pole flat are as follows: White/ground Brown/taillights Yellow/left...

  • Recommendations For 7-Way to 5-Way Trailer Wire Adapters
  • You can install a 7-way trailer plug on the trailer and only wire the 5 circuits you need based on our FAQ page on wiring, which I have provided a link to. If you go this route, you will need to trace each circuit on the trailer to determine its function and then wire it to the plug accordingly. I have provided a graphic showing the function of each individual circuit on the 7-way trailer plug. You also might need a new adapter to connect your 7-way plug on your vehicle to the 5-way...

  • Not All Boat Trailer Lights Light Up Using a 7-Way to 5-Way Adapter On a 2013 GMC Sierra
  • Since your truck is new, it is not likely that there is a problem with its wiring. So the adapter you already have could be faulty or there is a ground issue on the trailer. The functions of a 5-Way are as follows: The covered pin is ground. Next to it is the running light pin, followed by the left turn/brake light pin, then the right turn/brake light pin. And at the very end there is the pin for the electric reverse lockout solenoid on your surge coupler. Make sure that your 5-Way on...

  • Is 14 ga. Wire Sufficient for Wiring up a Brake Controller
  • I would strongly recommend you use a 10 gauge wire in place of the 14 gauge wire as 14 gauge wire is only good for 15 amps which will not be enough for your 2 axle trailer with 4 brake assemblies. For 10 gauge wire you could use our part # 10-1-1. I attached an FAQ article on wiring up a brake controller from scratch for you to check out also.

  • Coiled Length of the Hopkins Heavy-Duty Trailer Coiled Wire # HM47025
  • I went and pulled a Hopkins Heavy-Duty Trailer Coiled Wire # HM47025 from our warehouse to measure it and found that in its natural coiled state it measures 13-1/2 inches long. If you take the ends and point them away from each other but without stretching the coils it measures 19 inches long.
