Video Transcript for Roadmaster Tow Bar Wiring RM-146 Review

Today we're going to be reviewing part number RM-146. This is the RoadMaster's 6-Wire Flexo-Coil Kit. It's going to allow you to easily and effectively connect your motor home to your towed vehicle with the water, oil, and chemical-resistant electrical cord. The flexo-coil technology is going to allow the cord to extend more than 8 feet. Then it's also going to allow it to contract conveniently for storage and to resist dragging and tangling. The 6-Pole extension cord can be used for multiple towing applications. More than likely, it's going to be used for running power from your RV to your towed vehicle. It's going to come with 2 sockets.

One is going to mount to your RV and then one is going to mount to the towed vehicle for quick, easy hookup. The socket mounting brackets are going to be sold separately. You can find those right here at etrailer.com. You can see here how the sockets have the connectors here on the back for the wires to connect to. It runs through the rubber grommet or the rubber sleeve. Then, once it's mounted, all you've got to do is flip up the lid and then you can connect your extension cord directly to the connection points. It's got a nice spring-loaded lid, so it's always going to remain closed when that connected.

That way it's going to prevent any dirt or moisture from affecting the connection points. The flexo-coil cord, again, can expand more than 8 feet in length, yet still contract to prevent dragging and tangling. It's also going to provide convenient storage. We have silicone-injected plugs that are going to prevent corrosion. The electrical cord is resistant to water, oil, and chemicals. The plugs here on the cord have nice finger tabs on them. You can get a nice, secure grip on that. It makes for easy disconnect. 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-146. This is the RoadMaster 6-Wire to 6-Wire Flexo-Coil Kit. .

by:

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.




by:

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.


Comments
The FlexO coil kit is working just fine! Very pleased with the product!

by:

Katie in CS was extreamly knowledgeable and helpful. The quality of the Roadmaster 6 wire flexo coil kit is great.




by:

Customer Service rep Steve was outstanding to work with. Ordered the Flexo-Coil 6 wire kit and it was here within 3 days. Haven't tried it yet but it looks great and i'm sure it will work fine.




by:

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,




by:

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.




by:

Got just what I ordered no hassles and arrived when I was told it would...thanks great job and will order again when meeded




by:

Part came in as promised. Thank you for the excellent service. I have used you several times before with the same excellent service.

  • Which Pins of 6-Way are for 12 Volt Power and Ground
    I attached a picture that has a diagram of how a 6-way wiring harness is pinned out. The center pin is the 12 volt power circuit and the pin in the 1:00 position on the female socket as you face the open connector is the ground circuit.

  • What Gauge Wires are Used in the Roadmaster 7-Wire to 6-Wire Adapter # RM-146-7
    I spoke to my contact at Roadmaster and he informed me that the gauge wires that are in the RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit # RM-146-7 are 14 gauge and 16 gauge.

  • Does the Battery Have to be Disconnected to Flat Tow a 2015 Chevy Suburban Behind a Motor Home
    The battery should be disconnected because your 2015 Chevy Suburban has some feature that draws power when the vehicle key is in the towing position indicated in the owner's manual. If you leave the battery connected then what will happen is the battery will drain unless you stop frequently enough to let the Suburban motor run so the alternator can charge the battery back up. But there is a way to provide a maintenance charge to the vehicle battery when flat towing it with the battery...

  • Durability and Compatibility of Roadmaster 7-Wire to 6-Wire Flexo-Coil Kit
    Roadmaster over-builds their products and we have not heard of any issues with coiled extension kit # RM-146-7 so I believe that you will like it and that it will last a good long while. The 6-Way connector in the kit will fit Blue Ox base plates. If it is a snug fit or off just a little you can get a deep well socket to gently bend the posts on the base plate.

  • Wire Gauges Used for RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit
    You are correct. The wires for the light functions in Roadmaster Flexo-Coil Kit # RM-146-7 are 16 gauge and the 12 volt power and ground wires are the larger 14 gauge. I have linked a video review of this product for you.

  • Adding a 4- to 7-Way Adapter with Reverse Circuit for Boat Trailer with Electric Reverse Lockout
    Your trailer has an electric reverse lockout solenoid. When energized it will prevent the brake fluid from flowing back to the brakes so that you can back up. All you need is to install a 4- to 7-Way adapter such as # 37185 (if you need to replace the one you have). On the adapter there is a purple wire that you will need to tap into a reverse light circuit on your 2004 Honda Pilot. On the one you have the wire color may be different but as long as it is the one at the center pole then...

  • Wiring 4-Way to 7-Way Adapter Help
    Since I am not sure exactly what adapter you have the best solution I can provide currently is to have you check out the 7-way diagram I attached and wire up the wires of your 4-way to hopefully the same pin out. Otherwise the easiest to use adapter for your application is the part # 37185 which allows your 4-way to plug into it and converts it to a 7-way.

  • Where is RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit Assembled
    It is likely the RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit # RM-146-7 was assembled in the USA with components coming in from elsewhere. This is something that is pretty common to save consumers money; parts are sourced elsewhere but assembled in the U.S.

  • 4-Pole to 7-Way Adapter for 1998 Nissan Pathfinder
    You're exactly correct. If your trailer doesn't have brakes and you don't need the reverse lamp wire or the 12-volt feed you can use an adapter like the # 37185, plug it into your existing 4 pole and ground the white wire. The blue, purple and black wires can just be bundled up and zip tied up out of the way. The ground needs to be attached to the vehicle, to the frame or to a metal component in direct contact with the frame. I've linked to a product video featuring the # 37185 adapter. The...

  • Location for Installing Tow Lighting Socket on a 2016 GMC Canyon
    I attached a picture of a 2016 GMC Canyon front end that has a tow bar lighting socket installed in the front grille right above the license plate. That would be a great place to install the # RM-146-7.

  • Replacement Adapter Wiring For Mopar Flat Towing Harness On a 2019 Jeep Wrangler
    I do have one suggestion as we do not carry that Mopar specific harness. I recommend the Roadmaster 7-Wire to 6-Wire Flexo-Coil Kit # RM-146-7. For me this is a better route to go as the connections will be much easier attached and removed from your 2019 Jeep Wrangler Unlimited when you are setting it up for towing or removing it from tow. The coiled electrical cable will also allow for the wiring to sit higher while towing and will be less likely to drag on the ground and become damaged....

  • Brake Controller Port and Connector for a 2017 Tiffin Allegro Red
    To install the a brake monitor light on your 2017 Tiffin Allegro Red you will want to use the brake controller port that will be to the left of the steering wheel under the dash. The actual part number for that connector from Freightliner is PAC 12064754. This part should work for all Freightliner Chassis from 2004 to 2017. The connector is a 6 wire connector with a cap on it. I attached a photo showing it with the cap in place and removed. There are 5 wires going into the back of the...

  • Can Battery on 2015 GMC Terrain be Charged While Flat Towing it Behind a Motor Home
    Check the owners manual for the vehicle you intend to flat tow because you may or may not have to disconnect the battery to flat tow it. If you do not then it is possible that there is some feature that could drain the battery while in tow. And of course if you do have to disconnect the battery it would not drain. To provide a maintenance charge to the vehicle while in tow you would attach a charge wire to the battery and connect it to the Terrain side connector. I recommend using a 6-way...

  • How to Install a 6-Way Trailer Connector To Front of Flat Towed Vehicle
    It appears you are connecting your tow vehicle wiring to a 6-way connection like the RoadMaster 6-Wire Flexo-Coil Kit # RM-146. Making these connections is not difficult and I've attached a video and photo as well as linked an article to assist with these connections. You won't use the blue brake controller output location, but I do recommend connecting the 12V power using the Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 to maintain your battery while towing.

  • Kit and Instructions for Wiring Up Trailer to Convert 4-Way to 7-Way
    We have a kit that's designed specifically for upgrading a trailer's 4-way to a 7-way. For that you'd want the upgrade kit part # e99011 (if you don't have something like this already.) I attached a chart that details how this normally wires to a trailer for you to check out as well. In your situation the two wires with brown (and another color) are for the running light circuit but the rest SHOULD match color for color.

    At the beginning of the installation video (linked below) for the Roadmaster Universal Hy-Power Diode Wiring Kit, # RM-152, it states in conjunction with the Roadmaster 7-Wire to 6-Wire Flexo-Coil Kit, # RM-146-7. These are two separate components that work together. They are not packaged together as # RM-15267 or, each is able to be purchased separately as they can be matched with other options as well. These are not each vehicle specific.

  • Recommended 6-Way to 6-Way Coiled Flat Tow Umbilical Cord
    It sounds like you're looking for the RoadMaster 6-Wire Flexo-Coil Kit part # RM-146 which comes with the adjoining connectors as well but these can be saved for future use or discarded. The umbilical however is not offered without these adjoining connectors. In regards to safety cables, I recommend the RoadMaster 68" Single Hook, Coiled Safety Cables part # RM-643. If you need longer you can add extensions, RoadMaster 8" Safety Cable Extensions part # RM-910648-8.

  • Replacement Cable For Roadmaster Sterling Tow Bar
    The RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit # RM-146-7 can expand to over 8 feet. It keeps coiled shorter for compact storage and to keep from dragging while in use. If you are looking to run the cable through a tow bar channel, I recommend the Roadmaster 7-Wire to 6-Wire Straight Cord Kit - 6-1/2" Long # RM-98146-7 which is 78 inches long but can be trimmed to length.

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.

It will have you cut off your 4-Way on the Jeep and wire in a 6-Way receptacle to give you an additional charge line circuit for your 2009 Jeep Wrangler. It is a better wiring connection as well as the 6-Way has a stronger connection that won't pull from the socket when towing. The entire cord is coiled to keep from dragging while towing as well.
