Video Transcript for Roadmaster Tow Bar Wiring RM-164 Review

Today we're going to be reviewing part number RM-164. This is the Roadmaster Flexo-Coil 4 Wire Kit. This system is designed to connect the power from your RV to your towed vehicle so that the lights on your towed vehicle can be operated from the motorhome. Roadmaster electrical cords are water, oil, and chemical resistant, while the plugs are injected with a silicone to prevent corrosion. The Flexo-Coil design is going to expand over eight feet in length and it will contract for storage. It's also going to contract to prevent ground drag and tangles.

It's going to utilize the 4-pole round trailer connectors on each end. It is 4 wire to 4 wire. Internally it's going to contain sixteen gauge wires. It's also going to include two 4-pole sockets. One of these is going to go on your RV, the other is going to be for your towed vehicle.

They're going to mount in there for easy and convenient connection. If you need a mounting bracket for your truck or for your vehicle end that's not going to be included. You can find that separately right here at Etrailer.com with part number RM-910030. Also, keep in mind with the Flexo-Coil electrical cords are not to be used with Roadmaster tow bars with cable channel guides such as the all terrain models. For those tow bars you'll want to use the straight electrical cords. Again, the connectors have the nice finger tabs on it for easy connectivity.

The sockets have a nice spring loaded door that way when nothing's connected the door's going to remain closed, or the lid is, and it's going to help prevent any dirt or moisture from affecting the connection points. That's going to do it for today's review of part number RM-164. This is the Roadmaster Flexo-Coil 4 Wire Kit. .

The Flexo-Coil kit arrived sooner than I had expected and was exactly what I needed to complete the towing setup for my car behind the motorhome. It works perfectly and now allows me to charge the car battery while towing. 229348

Was surprised to receive the product so quickly--about 4 days. The wire was top quality, but much cheaper than I could buy from any RV dealer which I contacted; shipping was more economical than I had expected. This was my second order from you, and I was pleased with both, 156020

Very well made, complete kit with a good quality socket for each end. I found the cable a bit short, although the coiled section allows the wire to stretch, the coiling is very strong and resulted in the plugs being pulled out of the sockets unless I strapped the sprung loaded lid to the plug. 8185

  • Replacing a 4 Round to Both RV and Tow Vehicle Pigtail
  • The wiring for the male connector is the upper right (3 position) is Left Turn and Stop, Lower Right (1 Position) Ground, Lower Left (2 position) Tailights, and Upper Left (4 position) Right Turn and Stop. I have included a diagram showing the corresponding wiring that is explained in the installation instructions for your reference. Please make sure that you are wire by function not just by wire color, and I recommend testing the output on your RV to make sure this is done correctly....

  • Is there an Adapter to Go from a 4-Way Round Connector to a 6-Way Round Connector to Flat Tow
  • We do have a 4-Way round adapter but it goes to a 4-Way flat, # 47465. You could cut off the 4-Way flat end and wire in a 6-Way, # PK11609 for the vehicle end or # PK11604 for the trailer end, however your flat towing set up is arranged. We also have coiled kit # RM-164 which will allow you to replace the 6-Way end on the vehicle with a 4-Way round.

  • 4-Way Round Chrome Car End for a 2003 Jeep Wrangler To Tow Behind Motor Home
  • To install towing lights on your 2003 Jeep Wrangler you have two options. One way is to use a taillight isolating diode system, RM-154, to wire the motor home lighting system into the car's with diodes protecting both from damage. The second is to use a separate set of bulbs in the rear taillights, RM-155, that are run only from the motor home and do not interact with the vehicle wiring. This option requires enough space in the towed vehicles taillights to mount the extra bulb, but it eliminates...
