I ordered several Roadmaster components from etrailer.com to set up my 2014 Honda CRV as a toad. I can't say enough about how helpful etrailer's website is with all of their product review videos and installation videos. Their customer support is also top notch. Regarding this component (Towbar Wiring Harness), its good quality. I would have preferred a metal plug end for the 7 pin connector (like the other end of the 6 pin connector) but perhaps there is a reason it is plastic. Be careful not to screw in the set screw too deep as it will start to distort the plastic housing. The other recommendation is for Roadmaster to change the wire color key on the directions for the 7 pin. While the wires were prewired correctly, the schematic is wrong relative to the wire colors. Etrailer's tech information has a much clearer schematic for a 7 pin plug than what is provided by Roadmaster. All in all, this harness fits nicely in my Roadmaster Falcon All Terain tow bar channels and is the correct length. 234528

  • Installing Battery Charge Line To Power Tow Vehicle
  • The Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 and the Roadmaster Battery Charge Line Kit for Motor Homes # RM-156-75 will allow you to power your tow vehicle through a 6-way or 7-way wiring connection between vehicles. If you want a separate connector you can run a cord for that, but most people use the 12V pin or another unused pin and the 7 to 6-way cable to power their connection using a cord like the Roadmaster 7-Wire to 6-Wire Straight Cord Kit - 6-1/2' Long...

  • Wiring and Supplemental Braking System to Flat Tow 2017 Jeep Wrangler
  • The Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 is a 4-wire kit that gives you a 4-flat at the front of your 2017 Jeep Wrangler so what you can do is use cut off that 4-way and wire it into the Roadmaster 7-Wire to 6-Wire Straight Cord Kit # RM-98146-7; you are correct a straight wire is a better option than coiled for an all-terrain tow bar like your Falcon # RM-522. There are some other parts you will need as well, including Safety Chains # RM-643 if you do not already...

  • Availability of A 7- way Adapter to 6-pole Round Male Connector
  • The Hopkins Heavy-Duty, Coiled Trailer Connector Adapter - 7-Way to 6-Pole Round - Center Pin Auxiliary, item # HM47083, is designed to go from the the 7-way connector on a towing vehicle to a 6-way female connector on the towed vehicle. The center pin on the 6-way end is wired for 12 volt auxiliary function. If your towed vehicle has a male connector on it, to operate the brake lights when being towed, then you will need the RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit, item # RM-146-7,...

  • Wire Gauges Used in RoadMaster 7-Wire to 6-Wire Straight Cord Kit # RM-98146-7
  • I spoke with my contact at Roadmaster about the 7-Wire to 6-Wire straight cord, # RM-98146-7. All of the wires inside of it are 12 gauge.

  • 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...

  • Roadmaster 7-Wire to 6-Wire Straight Cord Kit without the 6-Way End Attached
  • It sounds like you are talking about straight cord kit # RM-98146-7. It plugs into a 7-way RV style connector on one end. the other end has just blunt cut wires and there is a 6-Way end that you would attach those wires to. It also comes with the mating 6-Way to plug into. I have linked a video review for you. You can also use bend bracket # RM-910030-5 or straight bracket # RM-910030 to mount the 6-Way receptacle part.

  • 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.

  • How Long is the RoadMaster 7-Wire to 6-Wire Straight Cord Kit
  • The RoadMaster 7-Wire to 6-Wire Straight Cord Kit, item # RM-98146-7, is 78 inches long, so that would not work for your application. You can put a cord together to get the length you need with a few parts. Start with the 6-Way Molded Trailer Wire Connector, part # H20036, which is 96 inches long. Then add the Pollak Black Plastic, 7-Pole Trailer Connector, part # PK12706. For the towed vehicle, you will also need the Pollak 6-Pole Round Pin Trailer Wiring Socket, part # PK11609, unless...

  • Replacement 7-Way Trailer Connector or 7-Way to 6-Way Harness for a Motor Home
  • We have several 7-Way to 6-Way round kits that you could potentially use but it sounds like you are looking for one such as # HM47057 with the straight cable and already assembled. But if you just need to replace the 7-Way end on the RV then you could do that it you want. If the 7-Way has a round plug at the back that just plugs into it then you could use # PK11893. Otherwise you would need to hardwire one in using # PK12-707E.

  • 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.

  • Replacing Tow Bar Wiring 4-Way Connector with a 6-Way on a 2011 Lincoln MKX
  • On the Hopkins tow bar wiring harness # HM56002 on your 2011 Lincoln MKX you will have to cut off the 4-Way flat end and hardwire each of the wires to the back of the 6-Way contained in kit # RM-98146-7. I have included a link to a help article that shows how various connectors are wired including a 6-Way and 7-Way to help. Remember that the 6-Way end at the front of the Lincoln is a vehicle side and not a trailer side.

  • Replacement Wiring Connector from Motorhome to Jeep for the Falcon All-Terrain Tow Bar
  • We do have a variety of wiring kits from Roadmaster that are used for flat towing with your Falcon All Terrain # RM-522. I am not quite sure which one you have but I will list the ones out that can be run through your tow bar. For blue wires we have the 7-Wire to 4-Wire Straight Cord Kit # RM-98164-7 and the 4-Wire Straight Cord Kit # RM-98164. If you have a larger connector on on your Jeep then we also have the 7-Wire to 6-Wire Straight Cord Kit # RM-98146-7 and the 6-Wire Straight...
