Video Transcript for Hopkins Tow Bar Wiring HM47043 Review

Today we're going to be taking a look at part number HM47043. This is the Hopkins Endurance Flex-Coil Trailer Connector. It's going to be the 7-Pole to the 4-Pole adapter. The adapter is going to convert your 7-pole, blade-style, vehicle-end connector for use with a 4-wire round connector on your towed vehicle. The connectors have the Nite-Glow function. They are going to illuminate the plugs when the tail lights on the tow vehicle are activated.

It's going to enable you to find your electrical connections in the dark and it's going to ensure that everything is connected correctly once those are lit. The coiled cable is a heavy-duty cable but it's also going to be very flexible. When fully stretched out it measures 8 feet in total length. It's going to let you connect the tow vehicle's socket and the trailer's plug with ease. It's also going to prevent wire from dragging on the ground. As you can see, this is 8 feet of wire but it's nice and compact so it'll also be very easy to store.

Here on the plugs they're going to feature large, easy-grip design that's going to make installing and removing the plug simple and easy. Those finger tabs are going to be found on each connector. That's going to do it for our review of part number HM47043. This is the Hopkins Endurance Flex-Coil Trailer Connector, 7-pole to the 4-pole adapter. .

Comments

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.

was having problems getting my toad lights to work properly and thought maybe the problem was with the motorhome, so today took both vehicles to Jim Campen Trailer Sales and had the wiring checked only to find that the Hopkins Coiled Connector is apparently wired different than the standard. They checked the wiring and connected a blue ox coiled cable and everything worked correctly, so said that the Hopkins cable is wired wrong. Had to buy a new cable. 215272

Although I have yet to place this item service, it appears to be exactly what I ordered and need. If it works as good as it looks I will be very pleased.

Well packaged and appears to be good quality. I'm looking forward to seeing how the polarity check light works which will save a bunch of time when hooking up 333595


Comments

The connector cable works fine. My only issue is that the coils are wound very tight and even at a short connection length the motorhome end can pull out. When not in use I hang it from the rafters in my garage with a 5 pound weight on it to try and stretch it out a bit.

Review from a similar Hopkins Endurance Flex-Coil in Accessories and Parts


Excellent service from etrailer. The Flex-Coil Adapter is said to stretch to 8' but it is such a tight stretch that one end pulled out of the motorhome recepticle the first time I tried it. I probably didn't have it fully seated in the recepticle and that the tightness of the coil will ease with use. It appears to be a well-made product. 58551


Comments

After a year, it still does the job but it never did stretch out as I had hoped and would sometimes pull out of the receptacles. I solved this by wrapping a hook

Review from a similar Hopkins Endurance Flex-Coil in Accessories and Parts


I was a little worried about the 8' foot being too long and dragging between my toad and RV, but the coils keep it up, it would have way too much tension beyond 7'. My RV came with a 7 blade connector so that end was no question and I choose the 6 Pole so I could take power lead across in case I ever had an application for power or charging. I did not hook up the power lead out of the toad connector, but could easily do so at any point in the future without needing a new connector or cable. The Toad end connector does light up and can be seen day or night. 80817

Working fine after a year of use, would not change a thing.

Review from a similar Hopkins Endurance Flex-Coil in Accessories and Parts


I bought this to replace my original dinghy connector cord. Very nicely made. Works fine but it needs to be just a few inches longer. On one occasion, after making a sharp turn, the tension on the cord pulled just enough on the coach end of the connection to slightly dislodge the plug and disconnect the circuits. Fortunately, I noticed there was no green pilot light on the control head of my dinghy brake system. Checked the plug connections and found the pug at the coach end slightly ajar. Pushed the plug back into place and all was fine. If the cord was 6" longer it would be perfect. 367646

Review from a similar Hopkins Endurance Flex-Coil in Accessories and Parts


Pluses are that the product is exactly as advertised, arrived on time at nearly half the cost of the blue coiled wire i needed to replace. Minuses are length, (it works but it pulls harder on the connectors than it would if it was a foot longer) and the red translucent molded connectors soften while in hot climates. Only time will tell how long they last. (unfortunately the wire isn't long enough to replace connectors with aftermarket ones) If manufacturer would harden the red ends and add a foot to the overall length they'd have the perfect trailer connecter for your toad. 87184


Comments

Thanks Patrick for great customer service and the best follow-up weve seen. Following a year of nearly continuous use we have had no negative issues with our coiled wiring pigtail. To my surprise the molded connectors are showing no signs of wear and the marginal length, although stretched tight, has not been an issue. I still believe adding 10-12 inches of lenght to the coil would be an improvement but overall the product has proved to be a wise purchase that we would definitely buy again.

Just what we were looking for, yet a way better price than retail. Half even with delivery, We're first time flat towers, looking to do things right the first time and save money if it turns out to not be the answer we're looking for. After searching online, we called for help/confirmation and the help she was. She called the manufacture to check a shorter lengtth, to no avail. Endedup it was perfect. Thank you. 156526


Comments

Great, I have tried to stretch it out, the constant retracting pull off the coiled construction seems to almost pull it out. I have grown more confident with its nature and secure it with a back up cable, to relieve some of the tension. The lighted ends also add confidence to the connection. Even my wife comments on its functionality. Too bad its wound so tight.

This is the 2nd time I’ve ordered from etrailer. Just as before, my order was here within 3-4 days. This time I ordered the electrical cord adapter.

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...

  • Is a 7-Round to 4-Round Adapter for Trailer Lights 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...

  • 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.

Regarding the wiring configuration there is really no standard way of wiring a 4-Way round connector. But if you are looking at the front of connector PK11410 the bottom left is ground, top left is left turn/brake lights, top right for right turn/brake lights, and bottom right is running lights like in the video I have linked.

  • 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.

  • 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 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.

The 4-Way end would plug into a vehicle side 4-Way since this item is used for flat towing a vehicle.
