Video Transcript for Roadmaster Accessories and Parts RM-146-7 Review

Today we'll be reviewing part number RM-146-7. This is the RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit. It's going to allow you to easily and effectively connect your motor home to your towed vehicle. The adapter cord can be used for multiple towing applications but it is going to be perfect for running power from your RV with the 7-blade plug to your towed vehicle or trailer with the 6-pole round plug. You can see here that the plugs have the easy grip, finger-pull tabs on it. It's going to make for very easy disconnecting. The Flexo-coil cord can expand more than 8' yet it's still going to contract to prevent dragging and tangling. The coil feature of the cord also makes it very easy to put the cord into storage.

It's going to have silicone-injected plugs that are going to prevent corrosion. The electrical cord is resistant to water, oil and chemicals. It's got a nice protected coating that goes around the wires. Now internally it's going to feature 14 and 16 gauge internal wires. It's going to come with a socket to mount to the towed vehicle side. You can see here all you got to do is remove the rubber sleeve and see the connections that you can make and then it's going to mount to the towed vehicle. It's got a spring-loaded lid on it that way it's going to remain close when not connected to prevent any dust or moisture from being able to affect the connection points.

It's going to come with the socket to mount to the towed vehicle side, as well as the mounting bracket. It also comes with some hardware. The hardware is going to be designed to mount the bracket to the towed vehicle. Also keep in mind that 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 today's review of part number RM-146-7. This is the RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit. .

The 7 to 6 coiled cable from etrailer.com came the next day and is exactly as described. After having ordered the same item from another professional online hitch-seller in Texas, paying for the item, and waiting 3 weeks without even a thank you for your order or status of the order, I finally had to call and leave a voicemail, then call back the next day to find out the order might ship on Friday. Needless to say I cancelled the order and called and spoke to Jan at etrailer.com who handled my order and verified each item was in stock and would ship the next day. Boy was I surprised when the driver delivered my package at noon the next day. A real Professional company. Buy with confidence. 92805

Perfectly. I always know the the electrical connection between the Motorhome and the towed vehicle will function as designed whenever I hook the two together.

Product Review: This is my second set of this kit. Setting up another TOAD. Very easy to install. Nice screw terminals with big enough holes for appropriate cable gauges. Everything you need is included. Even nuts/bolts. Yes, I could have just ordered the receptacle for my second TOAD, but having a second cable as a spare is not such a bad idea ;) Site Review: E-trailer is super easy to navigate. Easy to check out via CC or paypal...and you get follow up emails. No chasing after tracking numbers or order status' ... All diagrams and product data is available. If it isn't they'll get it for you ASAP. Top notch service IMO. 107293

Came in within a week (Value shipping) The only thing was the 6 wire female plug was very difficult to fit into the male end the provided for the vehicle and require having to force it on and off a couple of times to work it in so that it would go far enough to have the catch on the cap retain it in place. As for the wire it self, it is a little lighter weight than most but works just fine. 382696

I replaced the 4 pin connector with this 6 pin connector so I could hook up a battery tender for my toad. It arrived when promised and was easy to install after a quick chat with the tech support team at e-trailer. Based on reviews I've read, I should be in good shape for my trip from NH go FL this winter 160961

If you're pulling a toad vehicle this cable has the 12v power going to the proper pin for charging your toad battery (some don't). It is well constructed and should last for years. I added a little silicon sealer to the ends where the cable meets the connector to assure water won't get in. 131743

The coiled cord is a much better product than the straight cable supplied with my tow bar assembly. This allows for a straight run from the RV to the towed vehicle. The original had to be routed through channels and when being moved could easily pull the wires out of the connection. 481737

I bought a towing system from [retailer]. The light cable was damaged and I had to replace it. etrailer sold this cable for 65% of what [retailer] wanted. The shipped it out the next day and a few days later it arrived. Very happy with price, prompt service and product. 365789

  • Wiring Color Code On Ford Motor Home With 7-Way Connector And Car To Be Towed Has 6-Way Connector
  • The 6-wire and the 7-wire connectors will have the same color codes on six of the wires. The green wire is right turn/brake, the yellow wire is left turn/brake, the white wire is the ground, the brown wire is the taillights, the blue wire is electric brakes, and the black wire is the 12v power. The 7-way motorhome connector will have an extra auxiliary wire (purple) on the center pin that is used for reverse lights, 12v power, or reverse lockout for trailer brakes. There are two...

  • Recommendation for Disconnecting the Battery or Running a Hot Wire When Wiring a Jeep Toad Vehicle
  • You could route the power wire from the RV 7-Way trailer connector to the Jeep battery to help maintain the Jeep battery when towing. The problem is that the 12 volt circuit will most likely not be able to keep up with the amperage draw on the Jeep battery when towing, because of the distance from the RV charging system, and you would need trailer connectors to accommodate the extra wire on the tow bar jumper harness and the Jeep. I recommend installing an Auto Battery Disconnect, #...

The center pin on the 6-way end is wired for 12 volt auxiliary function.

  • Maintaining Battery in Vehicle Being Flat Towed Behind RV
  • First, you will need to confirm that the vehicle is suitable for flat towing. From what I have read on page # 319 through 321 of the owners manual, your GC can be flat towed if the transfer case has a Neutral position. If your 7-way on your RV has a 12-volt power feed (typically the pin in the 1:00 position), you can use that circuit to maintain your battery, however it will not charge a discharged battery. We offer a Flexo Coil Umbilical kit, part # RM-146-7 that would work well...

This cable is 7 feet when stretched. Between these two, I would go with the RoadMaster cable because the extra length may be needed. I have included...

  • Tow Bar Wiring Recommendation for Roadmaster All-Terrain Tow Bars
  • For the all terrain tow bars the non-coiled wires are recommended since the arms telescope and the all-terrain bars come with guides. But if you really wanted to use the # RM-146-7 with an all-terrain bar you can technically still do it. A better recommendation would be the # RM-98146-7 as this is a straight cord. However, I attached a picture that shows the # RM-146-7 being used with the Falcon 2 Tow Bar part # RM-520 which is an all-terrain tow bar.

I have the RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit, # RM-146-7, that is 8 feet long, but you would need to remove the 6-pole plug and attach the Draw-Tite 5-Flat Vehicle End Harness, # 20016, to give you a 5-Flat vehicle end or the Tow Ready 4-Flat Vehicle End Harness, # 18002, to give you a 4-Flat vehicle end.

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.

Then you could hardwire the included wiring to the 6-Way included with extension # RM-146-7. If you don't have to have a 7-Way at the front of the toad it would be a little easier. You could use Hopkins harness # HM56203 which just plugs in line with the vehicle tail light wiring. Then you could just use a 7- to 4-Way adapter on...

Depending on how far you are traveling and how much braking you are doing, it could be possible that the Blue Ox Patriot II # BRK2016 would drain your battery, especially if the ignition key has to be left in the on position.

Also yes you will be able to keep using your Roadmaster Falcon All Terrain Tow Bar # RM-522 to tow your Canyon.

Once you have the Roadmaster Universal Diode Wiring Kit, # RM-154, installed, the front 4-flat plug can be cut and removed. The 4 wires are then wired into the 6 pin connector.

The only time that you need to use specific wiring is when the wiring is built-in to the tow bar. If you don't already have the wiring on the vehicle then you ay be interested in the Roadmaster Kit # RM-15267 instead. This has the same connectors that you mentioned plus the diodes and wiring needed for a complete installation. This kit is pretty universal,...

  • 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.
