Video Transcript for Hopkins Wiring - Wiring Adapters - HM47025 Review

Today we're going to review part number HM47025. This is the Hopkins Endurance Flex Coil Seven-Way RV Blade to Five-Wire Flat. This flex coil adapter provides increased durability and the additional length that may be necessary to reach between the tow vehicle socket and either the trailer or the tow vehicle's plug. In addition, the flex coil adapters use a Nite Glow and that's the red portions of both connectors. Basically, they will illuminate on activation of the tail lights, and this will enable the user to find electrical connection in the dark and it shows that the vehicle's trailer wiring system is working properly. It is a heavy-duty coiled cable, has a weatherproof jacketing. Right here on the seven-way, you can see it has a nice easy-grip handle, makes it easy to install and remove. Both of the red connectors are a translucent Nite Glow connector.

They do light up when you're connected to the tail lights. It also uses the tin-plated terminals on both connectors for corrosion-resistance. This can be stretched. When it's fully stretched, it goes about three feet in length. Again, has the seven-blade RV blade on this side that goes to the vehicle and then the five-way wire flat for the trailer. Basically, the five-wires, when it's on a trailer, would usually be the extra, the four, the normal four-way flat, is for lighting functions and then the extra pin on a five-way is actually the reverse light circuit.

What that does is, on some trailers, they'll have an electric lock-out that'll lock out the brakes when you're backing up, so you need that reverse light circuit. That's why you'll have a five-way on the trailer. You can actually still plug a four-way outlet into this. It's just that on a four-way, the reverse light circuit is not required, so if you just plug the four-way in, starting where the ground plug is here and just don't use that end pin, which is the reverse light circuit. You can still use a four-way on this, also, if you like. That should do it for the review on part number HM47025, the Hopkins Endurance Flex Coil Seven-Way RV Blade to Five-Wire Flat. .

Do you have a question about this Wiring?


  • Recommended Flat Towing Set-up For 2015 Jeep Wrangler Sport
  • For your 2015 Jeep Wrangler Sport, since you already have your Roadmaster StowMaster Tow Bar, # RM-501, we will start with your base plate needs. The # 1175-1 Roadmaster base plates you have are not compatible with your Jeep, so I recommend going with the Roadmaster EZ4 Base Plate Kit - Removable Arms, # RM-521448-4, which is compatible with your Jeep and your current tow bar. For your Jeep tow wiring, I recommend the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles, # HM56200....

  • Wiring Adapter to Convert Vehicle 7-Way to 5-Pole Flat Connector for Boat Trailer
  • Usually a factory tow package on the Suburban has a 7-way type trailer socket, like # HM40975. There are 6-pole wiring products out there but these have a very different appearance. If you refer to the linked article on wiring you'll be able to see each type and confirm which you have. Often the center contact on a 7-way, which carries a reverse light signal, is not counted as it has a different appearance than the other contacts in the socket. If you do indeed have a 7-way with a reverse...

  • What Is The Difference Between These Flex-Coiled Wire Adapters by Hopkins - # HM47025 And # HM47075
  • These Hopkins wire adapters, Item # HM47025 and Item # HM47075, have similar functions. Both are heavy-duty, coiled cable with weatherproof jacketing. Both have easy-grip connectors and light up when connected. Both are 3 foot when stretched. Both adapt a 7-Way connector to work with a 4-Way or 5-Way flat connector on a trailer. One difference is that the The Hopkins Endurance Adapter, Item # HM47075, has a 3-year limited warranty. I have attached videos for you to check out.

  • 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...

  • Availability of 8 Foot Flat Towing Umbilical with 7-Way on One End and 4-Pole Flat on the Other
  • There's not an available 7-way to 4-pole flat umbilical like what you're looking for, but I do have some easy solutions for you. The Hopkins Nite-Glow 7-way to 5-way flat coiled adapter, part # HM47025 will work with either a 4-pole or a 5-pole trailer connector. It would plug right into the connector at the front of the towed vehicle provided by the Hopkins Towed Vehicle Wiring Harness you referenced, part # HM56302. If the unused socket bothered you, you could cover it with a small...

  • 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...

  • 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.

  • Installing Battery Charge Line for Flat Towed Vehicle with 4-Way Connector
  • I do have a solution for you, however you won't be able to run a charge line from the 5th pin on the Hopkins Heavy-Duty Trailer Coiled Wire Adapter # HM47025 that you referenced. The 5-Way on this adapter will plug in just fine to the 4-Way on your toad but the open 5th pin carries the reverse light function and not the 12V power circuit from the 7-Way on your RV. In order to add a charge line to your setup the best solution will be to use the Roadmaster 7-Wire to 6-Wire Flexo-Coil...

  • 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...

  • 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...
