Video Transcript for Checking Out the RoadMaster 4-Wire Flexo-Coil Cord Kit with Mounting Bracket

Today we're going to be reviewing part number RM-1644. This is the RoadMaster 4-Wire Flexo-coil Cord Kit with Mounting Bracket. The four pull extension cord can be used for multiple towing application, which will make it perfect for running power to your RV to your towed vehicle. That way, you still have access to all the lights and turn functions and stop and everything that you need to translate from the motorhome signals over to the towed vehicle signals. This is a 4-wire to 4-wire design. It's got the easy to grip finger tabs for easy disconnect. The Flexo-coil cord can expand more than 8 feet, yet still contracts to prevent dragging and tangling, also making storage very easy.

You're also going to get two sockets. One's going to mount to your RV and one's going to mount to the towed vehicle for quick, easy hook up. They're going to feature the spring-loaded lid. That way the connections are always going to stay protected from dirt and moisture. It's going to come with one bracket.

This also comes with the hardware to get it mounted. Basically, it just holds one of the sockets in place, probably on your towed vehicle is where you're going to install this and it's just going to keep the wires easily accessible, that way all you have to do is flip open the lid once you get it mounted. Plug in the Flexo-coil cord to the towed vehicle side and the other end's going to go to your RV or motorhome. Everything's going to be connected and ready to go. We have silicon injected plugs.

These are designed to help prevent and stand up well against corrosion. The cord is resistant to water, oil, and chemicals. You also want to keep in mind that the Flexo-coil cords are not intended for use with RoadMaster All-Terrain Tow Bars or any other tow bar that includes cable channel guides. Only straight cords should be used with those models. That's going to do it for our review of part number RM-1644. This is the RoadMaster 4-Wire Flexo-coil Cord Kit.

  • Flat Towing Wiring Extension 6-Pin To 6-Pin
    The RoadMaster 6-Wire Flexo-Coil we offer comes in a kit as part # RM-146. This extension comes with the vehicle-end connector to mount to the RV and towed vehicle. I have attached an installation video of these connectors being installed on a 2014 Honda CR-V. If you do not need the vehicle-end 6-pin connectors, you could use the Hopkins Heavy-Duty Trailer Coiled Extension # HM47055. I have attached a review video of this extension for you.
