Cathy T was a FANTASTIC help in finding the exact right product that we needed!!! It's sometimes difficult to understand what we need because what we may call an "extension cable," may actually be labeled as a "wiring adapter" or "trailer connector." She was very patient and thorough as she found us the precise product for us. She was also knowledgeable about Jayco trailers, knowing their uniqueness, which also helped her in finding us the right product. And this product is absolutely the exact item we needed!! We luv it cuz it's easily visible for us, as well as law enforcement on the road!! Thank you for your expertise and great selection which provided us with what we need!!


makes for a faster hook-up from Truck to trailer. What is outstanding is the plug lights, when connection is made.


excellent product, perfect fit

still doing what I need it to do

  • 7-Way to 4-Way Adapter Recommendation for Connecting from RV to Towed Vehicle
    The Hopkins Nite-Glow 7-way to 4-way flat coiled adapter, part # 47015 will work with the 7-way on your RV and then would plug into the 4-way. It would plug right into the connector at the front of the towed vehicle.

  • What Applications is the Flex-Coil Adapter part # 47015 Designed for
    The Flex-Coil Adapter part # 47015 that you referenced is designed to plug into a trailer 7-way and convert the trailer wiring signals to a 4-way flat connector. As long as your truck has a 7-way (it would look like part # 37185) and your trailer has a 4-way this adapter would work well.

  • How Does 4-Way Flat Trailer Connector Fit In Vehicle-End 5-Way Trailer Connector
    I have attached photos of a 5-way vehicle end connector and a 4-way trailer connector you can check out. One photo shows them separated and the second photo shows what they would look like when attached. As you can see the 4-way will fit just fine in the 5-way flat connector. To keep moisture and dirt out of the 5th pin connector you could use electric tape to cover the opening or use a bit of dielectric grease like part # 11755 in the open pin. I recommend the 7-Way RV to 4-Way or 5-Way...

  • Availability of Flat Towing Umbilical Cable Longer Than 3 Feet in Length
    We do offer some longer coiled cables that would work for you. Wesbar offers a 7-way to 5-pole coiled adapter, that will also work fine for a 4-pole. For a 4 foot length, use part # 787207. For an 8 foot length, use part # 787196.

  • 4-Way to 7-Way Adapter Needed for 2018 Subaru Forester Towing Trailer with 7-Way
    Glad to hear that you are happy with the Curt Trailer Hitch Receiver # C12100 and the T-One # 118467 for your 2018 Subaru Forester! In regards to the Hopkins Adapter # 47015 that you referenced, unfortunately you are correct that it cannot be used in reverse. You need a 7-Way receptacle which would need to be mounted on the Forester end of your towing setup. If you are concerned about having to drill into anything I have the perfect solution for you to avoid doing so. The best adapter...

  • Recommended Wiring Extension to Use With Curt Hitch Extension
    I have several options for wiring to use with the Curt Hitch Extension # C45048 depending on what kind of connection you need. If you are looking for a 7-way extension then I recommend the TorkLift Wiring Harness Extension for 32" SuperTruss Hitch Extender - 7-Way RV # TLW6032. For a 4-way extension we have the Hopkins Endurance Easy-Pull 4-Flat Extension w/ 2 Grip Rings - Vehicle and Trailer Ends - 48" # HM47114. Finally if you're going from a 7-way to a 4-way I recommend the Adapter...

  • Where To Mount Breakaway Switch And Tow Bar Wiring Kits On A 2019 Dodge Ram Rebel
    The brackets on your Roadmaster Direct-Connect Base Plate Kit # RM-522205-5 are for connecting safety cables in the event of a disconnect/breakaway so you won't want to use those spots for the wiring. The best place to mount your emergency disconnect and 4-pole connector is in the grille above the skid plate. You can run the cables through and zip-tie them in place onto the grille. For the 4-pole I recommend using the 4-Flat Mounting Bracket Item # 18144 then add a short bracket # 18140...

  • Recommended base Plates And Adapter For 2015 Ram 1500 To Work With Excali-Bar Tow Bar
    If your Ram 1500 is a Sport or Express model, the base plates I recommend are part # RM-298-1. If your truck is not the Sport, Express, Laramie Limited, or Rebel, the base plates I recommend are part # RM-52289-4. You will then need the adapter # RM-032 that will let you use the base plates with your Excali-bar ll tow bar. The tow bar lighting kit I recommend is part # RM-154. This includes a 4-way connector to attach to your motorhome. The flex-Coil adapter I recommend to install between...

  • Recommended Hitch Cargo Carrier with Lights and Anti-Rattle Device for 2016 Chevrolet Suburban
    To select the best option in a folding 2-inch hitch cargo carrier for use on your 2016 Suburban you will want to take note of one clearance dimension, the distance from the hitch pin hole to the rear-most part of the vehicle (probably the bumper cover). This dimension will allow you to choose a carrier that will still fit nicely when you have it folded up in the storage position. The linked article illustrates taking this simple measurement. The etrailer # e98874 will offer 9-1/2 inches...
