Video Transcript for Review of Roadmaster - Tow Bar Wiring - RM-1046-R

Today's we're gonna take a look at the Roadmaster 6-wire Flexo-Coil Cord. Now this will replace a damaged 6-wire electrical cord on the Roadmaster Flexo-Coil kit part number RM1466. Now we do sell those kits separately on our website. This is the coil cord only. The connectors we do sell separately. Does require the 6-pole round trailer connectors part number RM-910030-8.

Again, we do sell those separately also, and they are listed on this product page as a related product.Now this is a 6-wire extension cord that can be used for multiple towing application. Perfect for running power from your RV to your tow vehicle. It easily and effectively connects your motor home to your tow vehicle, and it's a water, oil and chemical resistant cord. Does use the Flexo-Coil technology which you can see it allows the cord to extend more than 8' in length and then contract conveniently for storage, while also prevents dragging and tangling. But that should do it for the review on the Roadmaster 6-wire Flexo-Coil Cord..

  • Parts Needed for Wiring Extension with Vehicle End 6-Pole Connectors
    In order to have a wiring extension with 2 vehicle end connectors on it, you will want to create your own extension. We do not carry a pre-wired extension with 2 vehicle end 6-pole connectors. You will want to use 2 of the Pollak 6-Pole, Round Pin, Trailer Wiring Socket # PK11609. These will need to be wired to either end of a length of 6-wire. You can use the Deka Wire - Jacketed 6-Wire # DW04906-1. This wire is sold by the foot, so you can order the best length for your application....

  • Wiring And Flat Towing Recommendations For 2004 Jeep Cherokee Towed With Motorhome
    To complete the wiring as you wanted I first recommend installing the Tow Ready Diode System, part # TR118821. Then cut the 4-way plug off the harness and install a 7-way plug like part # PK12-707E. For a mounting bracket I recommend part # PK12711U-26. I recommend using the RoadMaster 6-Wire Flexo-Coil Cord, part # RM-1046-R and adding two male connectors like part # A7WCB.

  • Is there a 7-Wire Hopkins Flex-Coil Cord without Trailer Connectors Attached
    There is a 6-wire Flexo-Coil cord, # RM-1046-R, with just the wires but there is no 7-wire option. There is also a 4-wire version, # RM-1064-B. The # HM47075 cable is only going to have 5 wires inside since the one end can only be used on a 5-Way or 4-Way flat trailer connector. The wires inside the 6-wire # RM-1046-R is 14 gauge. This is not the ideal size for brake or 12 volt line. You could just use jacketed 7-wire, # DW04914-1 which has 6 wires that are 12 gauge and 1 that is 10...
