Video Transcript for Roadmaster Flexo-Coil 4 Wire Kit Review
Today we're going to review the RoadMaster Flexo-Coil 4-Wire Kit. Part #RM-164. With this part number, this is what you get. Two round 4-pole ends on the cord and two matching sockets. This is great for electrical setups between your RV and your towed vehicle that just use lights. Your circuits will be left turn, right turn, running lights and ground. Right now it's pretty compact. You can see it's all coiled up.
This will stretch out a maximum of 8 feet. Now the outside of the cords are designed to be water, oil and chemical resistant. Also inside the plug, if we could show you, would be injected with silicon to help protect the insides. As you can see in our connectors here that go on your RV and your towed vehicle, it doesn't come with any brackets. So you want supply some form to hold it up there in place. This is a bracket that will work with a 4-pole connector.
It also comes with hardware to attached to bracket to the 7-pole connector. Although you do have to supply your own hardware of two holes for wherever you mount your bracket to. In a typical application, this is what a bracket and a 4-pole connector looks like. We can see our four pins that are constructed out of brass inside a plastic fitting inside this whole connector. When you put these together, always make sure that this tab right here goes towards the top. It fits in this little D tin right here on the lip.
There is also a key on the bottom to fit with this slot. It's tempting to remove it by just grabbing the cord. You can get finger hold on the sides here so I can pull it apart like that. This is a Fleco-coil and actually holds it's shape and takes up the slack when it's being used between your car and RV. With that in mind, you want to make sure that these are not to be used with the RoadMaster tow bars with the cable channel guides such as the all terrain models. With those tow bars use the straight electrical cord. All right and that will finish for RoadMaster Fleco-Coil 4-Wire Kit.
Part #RN-164.

I have used RM products for years, and never been disappointed. This cable will replace a 20 yr old one that has been damaged and worn. Have not used new one yet. Expect it will be excellent.

Quick response, up to the minute tracking of shipping. Will do business with these folks again.

Works great with the extra length. I have an extended hitch length due to towing a small car and therefore had to add a 4 inch drop which added extra hitch length. My precious umbilical cord got damaged by being to short and pulling out.

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.

- Replacing a 4 Round to Both RV and Tow Vehicle PigtailThe 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.

- 4-Way Round Chrome Car End for a 2003 Jeep Wrangler To Tow Behind Motor HomeTo 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 cars 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...

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.
