This cord adapter is just what I needed to hook my motorhome electrical to my Jeep. it is well made and should last along time.Its enclosed lighting system is great when hooking up a night. Ordering and shipping with etrailer is always easy and a pleasure. 821719

This unit replaced one that failed near the end of the warranty. Unfortunately, it appears to be failing in the same manner, the plug at the 4 pin end is starting to pull away from the cable and I assume will stop working. The cable is nice looking at a reasonable cost, but the ends are not well enough made to handle the constant tension of the wire in this application. 774686

The first one of these lasted about 18 months. The harness started to uncoil and the yellow insulation cracked and split exposing the wires. Warranty is 3 years. Maybe I just got a bad one. I have ordered a replacement. 545421

Works as good as the day it was received. The yellow insulation has frayed quite a bit, but I wrapped the frayed areas with a good quality electrical tape which has taken care of the issue. Other than the fraying, have been highly satisfied with the product. Would buy again.

  • 7-Pole To 4-Pole Trailer Connector Adapter To Flat Tow 1997 Suzuki Sidekick
    From your photos you have a 7-blade connector on the RexAir and a 4 pin round connector on the 1997 Suzuki Sidekick. The blue wire in your photos is a 4 pin to 4 pin connector which will not work to connect the RV and the Suzuki. All you need is a 7-pole to 4-pole adapter part # HM47043 to connect the RV to the Suzuki.

  • Correct Orientation for Plugging in 4-Way Round Side of Flex-Coil Trailer Connector Adapter
    When installing the 4-Way Round connection of the Hopkins Endurance Flex-Coil Trailer Connector Adapter # HM47043 you want to make sure that the thick square part is facing the ground as you can see in the attached photo. I have also attached a photo of a typical 4-Way Round connection for both the trailer and vehicle that you can use as a reference. Typically a spring-loaded lip on a cover will help keep the connector from accidentally falling out. I can guarantee this as I don't know...

  • 7-Way to 4-Way Round Adapter Recommendation

  • 7-Way Commercial Truck Plug to 4-Way Wiring

  • Adapter Recommendation to go From 4-Way Round to 7-Way Blade
    If you need an adapter to go from a 4-way round female socket to a 7-way blade socket the Hopkins Endurance Flex-Coil Trailer Connector Adapter w/ Nite-Glow # HM47043 is the correct coiled adapter for that. There isn't a specific adapter to go from a 4-way round to a 7-way round since the 4-way round isn't that common.

  • Availability of 4-Way to 7-Way Adapter
    There sure is! To connect your tow vehicle that's equipped with a 4-Way flat to your camper that has a 7-Way connector I recommend using the Hopkins Adapter # 37185. This will plug right into the 4-Way on the vehicle to provide you with a 7-Way at the other end. If you only need to power the trailer's basic signal lights then you only need to ground the white wire to a clean bare metal surface and the remaining wires you see coming from the adapter (blue, black, and purple) can simply...

  • What Type of Socket Does 4-Way Round Side of HM47043 Attach to

  • Trailer Wiring Adapters Available for 7-Pin Flat to 4-Pin Round Connectors

If you're looking for a wiring adapter to allow you to connect a trailer with a 4-Way flat connector, like # 18004, to your vehicle's end 7-Way blade-style socket, like # PK11893 we have an adapter that will work great. For this set-up, you can...

  • 7-Way to 4-Way Round Wiring Adapter to Flat Tow a 2001 Honda CR-V
    We do indeed carry a 7-Way blade style to 4-Way round adapter. It is # HM47043. This is a coiled cable that can stretch to 8 feet long. The 7-Way end plugs into the RV and the 4-Way end to the vehicle. The diode kit you mentioned is # 154-792-118158. For a 4-Way receptacle to mount on the front of the CR-V use # PK11410. It looks like you will have to pull fuses to flat tow the CR-V. Consult the owners manual to confirm. To avoid having to pull a fuse every time you can install a fuse...

  • Recommendations for Using a Roadmaster Sterling Tow Bar on a 2001 Honda CR-V

Other customers have mentioned that there are various pieces missing or forgotten especially when buying used tow bars. To flat tow your 2001 Honda CR-V behind your motor home you will need the following components: Tow Bar (your used Sterling is an excellent choice) Towed Vehicle Base Plates (compatible with your 2001 Honda CR-V, and your...

  • Is Wiring Adapter Available to Connect 4-Flat and 4-Round to 7-Way Vehicle End Connector
    I have a couple of solutions for you, but there is no adapter available that will allow you to connect both the 4-Way flat and 4-Round connectors to your motor home's 7-Way blade-style connector. If local laws don't require you to use both the lights on the tow dolly as well as additional lights, I recommend only using the lights that will be most visible on the road, likely the additional taillights. We have one wiring adapter that will allow you to connect the 7-Way blade-style connector...

  • Will Hopkins Endurance Flex-Coil Trailer Connector Adapter Work With Heavy-Duty 4-Way Connector
    If you have a round 4-way connector, the Hopkins Endurance Flex-Coil Trailer Connector Adapter w/ Nite-Glow, part # HM47043, should work just fine. This adapter plugs into a 7-pole blade-style connector for use with a 4-wire round connector on your towed vehicle. This also has a Nite-Glow feature so you can make your connections even in the dark. I have attached a video you can check out for this connector.

  • Does 12 Volt Charge Circuit Run Through Hopkins Adapter 7-Pole to 4-Pole # HM47043
    The Hopkins Endurance Flex-Coil Trailer Connector Adapter w/ Nite-Glow - 7-Pole to 4-Pole # HM47043 that you referenced does not carry the 12 volt power circuit since the one end only has a 4-way. Because of that you would not be able to charge your battery through this adapter. We do have the charge line kit from Roadmaster part # RM-156-25 which is designed for what you are looking to do that you'd need to use with the # HM47043 since it carries the light circuits.

  • Parts Needed to Flat Tow GMC Canyon with Blue Ox Base Plate Installed
    That's a Blue Ox base plate kit you have installed on your 2017 GMC Canyon so you'd want to use a Blue Ox Tow Bar like the Avail part # BX7420 which is one of the best and easiest to use options out there. Some tow bars are hard to connect/disconnect to and don't allow the vehicle to track well behind the tow vehicle but the Avail does a really great job with this. To connect the lighting solution you have now on the truck you'd need a coiled 7-way to 4-way round like the part # HM47043....

  • Wiring Adapter Recommendation to go From RV 7-Way to Toad 4-Way for Lighting
    Sounds like you are asking how to hook up the magnetic tow bar wiring you have to your RV that has a 7-way flat RV connector. Your RV having separate turn signals from stoplights will not be an issue. The 7-way on your RV will already have the turn signal circuits converted to combined so that it matches your tow bar wiring. If you have a 7-way flat connector on your tow vehicle you would want the part # 787196. If your lights have a 4-way round you would need part # HM47043 instead.

  • Is a 7-Round to 4-Round Adapter for Trailer Lights Available?
    I can offer you a solution, though a 7-round to 4-round adapter is not available. What you will need to do is create your own by wiring a 7-round trailer end connector, # PK11700, and 4-round vehicle end connector, # RM-910030-1. I recommend going with the 14 gauge, Deka Jacketed 4-Wire, # DW04923-1, which is available per foot so you can get the amount you need. If you have an RV-style connector (which is often referred to as a 7-round), then the part you would be looking for is the...

  • What Is The Wiring Configuration For 4-Way Round Connector
    On a flat 4-way connector, the standard function is Green is the right turn signal and brake, Yellow is left turn signal and brake, White is ground, and Brown is the running lights, used when the headlights are on. You may want to test the wires for function just to be sure. You can use a circuit tester like part # 40376 for that. I have attached a photo that shows typical wiring for a 4-way round connector.

    If the 4-way on your RV is a round socket, you will need to wire the Roadmaster 4-Wire Straight Cord Kit # RM-98164 to match the wiring on your RV function for function. Since RVs do not commonly come with 4-way round connectors, it is hard to say how the 4-way is wired. You can use a circuit tester like # 40376 to test for the wires functions. If the 4-way on the RV is not round, I recommend using the Hopkins Endurance Flex-Coil Trailer Connector Adapter # HM47043. This wiring extenstion...
