Video Transcript for Roadmaster Accessories and Parts RM-164-7 Review

Today we're going to be reviewing part number RM-164-7. This is the RoadMaster 7-wire to 4-wire flexo-coil kit. The adapter cord can be used for multiple towing applications. It's going to be perfect for running power from your RV with the 7-way plug over to your towed vehicle or a trailer, by connecting the 4-wire plug. It's going to come with the mounting sockets. This one right here would be for the 7-way socket. It would mount through there, and it's going to allow you to connect the socket of the flexo-coil cord.

Same thing for the other side. This is going to be the socket that's going to hold your wires on your vehicle. It's going to allow you to connect our 4-wire plug directly in there. That way, you can feed power from your RV over to your towed vehicle. The flexo-coil cord can expand more than 8 feet, yet still contract to prevent dragging and tangling. It's also about making it easier for storage. As you can see here, with it fully coiled or contracted, it's only going to give us an overall length of about 15 inches.

That can be all folded up and moved to a nice stored position; whatever way you want. That's a very advantage to have for you; just a great feature to have when it comes to storage, and to prevent it from dragging once your connections are made. The plugs are going to be silicone-injected. That's designed to help prevent corrosion. The cord is going to be resistant to water, oil, and chemicals, and it's going to feature color-coded, 16-gauge inner 00:01:34 wires. Please keep in mind that the flexo-coil cords are not intended for use with RoadMaster all-terrain tow wires or any other tow wire that includes cable, channel guides. Only straight cords should be used with those models.

In the packaging, it's going to come with a nice little diagram that's going to indicate the socket pin numbers, as well as their function, on both the 7-wire and the 4-wire. That's just great to have. That's going to be found towards the back of the packaging that this system comes in. That's going to do it for our review of part number RM-164-7. This is the RoadMaster 7-wire to 4-wire flexo-coil kit. .

I recently purchased a Blue Ox tow bar, towed vehicle brake system and three wiring harnesses for towing my Jeep Liberty with our motorhome. etrailer.com was my first choice for the purchase for these items worth almost two thousand dollars. Even though these prices were set by the manufacturer, I knew I could trust these folks. Their salesmen, (in this case Wayne H.), are more than just order-takers. They know what they are selling and are a good source of information on a variety of related products. When Wayne wasn't available for follow-up discussions, the operator took my cell number. Surprisingly, Wayne got back with me right away and supplied me with his direct line in case I had any questions. I've had experience with others dealers who don't get back for hours if at all. Bottom line: etrailer.com will continue to be my first choice for RV and other related items. 178129

Was looking for a 7 pin to 4 pin Flexo Coil Kit. Found it on line at etrailer at ma reduced price I was willing to pay. When I checked with my local RV dealer, He said I needed to buy from e trailer. Their price was below his cost.. 168906

I needed to order a replacement connector and a Blue Ox tow bar. The website was extremely helpful, but I had some questions and called. Kevin helped be out on the order, getting me just what I needed. I had the items before the weekend, extremely impressive! The tow bar and electric connector are excellent products and a great way to tow my jeep behind our Nexus RV. 374037

I've only used this item for a week so I cant say if it maintains its coil. The only thing I'm not happy about is the 4 prong male / female end. It doesn't lock in good enough in my opinion. I feel with a slight tug or bouncing movement it will dislodge itself and drag on the ground. So what I do is wrap a velcro strap around it to make sure that does not happen. Should one have to do this? You decide. I did like the attach method of the wires inside the female connector. Easy and solid 452082

I am customizing my Jeep Wrangler to tow behind my motorhome. This coiled electrical plug was exactly what I ordered and needed. Excellent customer service always! I'm grateful to have etrailer to help me when I need it. I will always go to etrailer first! 321775

I ordered this item to replace a similar harness that had been stolen out of my truck, but was very disappointed to discover that the 7-pin plug would not engage properly with the OEM receptacle on my Dodge truck with factory hitch and tow package! The spring loaded cover on the receptacle would not engage the retaining tang on the plug, and when I finally forced the plug in far enough for it to engage, the left rear turn signal and brake light on the trailer did not work. The plug on the previous harness fit perfectly, so the location of some of the 7 female slots on the Roadmaster plug was evidently not correct. I paid a premium to return it ASAP via UPS expedited shipment over the Memorial Day weekend; I eventually received a warranty replacement 17 days later. At least the 7 pin plug on replacement harness does fit correctly. I will admit that the metal 4 pin plug and receptacle on the trailer end of the Roadmaster harness are much better quality than the cheap plastic parts on the original harness. I would recommend that anyone buying one of these Roadmaster cables first check the fit of the 7 pin plug with your hitch receptacle before bothering to hook up the 4 pin receptacle for the trailer, in case you have to return it! 261794

After having my boat trailer powder-coated blue, this was a good match for the trailer. And I like being able to disconnect the entire harness. 451711


Comments

We sold the boat and trailer in August ‘18. The guy who bought it was impressed that I had completely rebuilt the trailer and that it had led lights and color matched cables instead of chains.

  • Flat Towing Setup Recommendation for a 2014 Honda CR-V
  • We have everything you would need to flat tow your 2014 Honda CR-V. First lets start with a base plate kit as that is the attachment point on the vehicle. For that you would want the Blue Ox Base Plate kit part # BX2258. I attached an install video for you to check out as well. The Blue Ox Alpha # BX7365 is the most popular tow bar we offer that has been confirmed to work with the base plate kit so it should work very well. It also comes with safety cables. For trailer wiring you...

  • What Would I Need to Flat Tow my 2005 Chevy Aveo
  • I did some checking and it looks like manual transmission 2005 Chevy Aveos can be flat towed without issue, but the automatic transmission Aveos can not be flat towed. You would have to check your owners manual to see if a tow dolly like a RoadMaster Tow Dolly with Electric Brakes, part # RM-2000-1 could be used. I attached installation instructions below for you to check out also. If you had a manual transmission you could use a RoadMaster Tracker Tow Bar - 5,000 lbs, part # RM-020,...

  • What Equipment is Needed to Flat Tow 2004 Jeep Grand Cherokee
  • To flat tow your 2004 Jeep Grand Cherokee, you will need a base plate kit, a tow bar, safety cables, towed vehicle wiring, and a supplemental braking system. It is also likely that you will need a wiring extension to connect the RV's wiring with the Grand Cherokee's and a high-low adapter that will allow you to have the tow bar level while towing your vehicle. Since you are looking at the previous generation of the Roadmaster Falcon Tow Bar # RM-520, it will be easiest to connect the...

  • Wiring Extension for Flat Towing a Vehicle Behind Monaco RV with 7-Way Trailer Connector
  • In order to determine the proper set up for your new towed vehicle (called a toad; the vehicle you will be flat towing behind the motor home) I would need to know the year, make, and model of that vehicle. Most of the tow bar wiring uses a 4-Way flat trailer connector with a few exceptions. Since your RV has a 7-Way trailer connector ideally you would use a cable that has a 7-Way on one end to plug into the RV and a matching connector on the other end for the tow bar wiring/lighting...

  • How Long is the RoadMaster 7-Wire to 4-Wire Straight Cord Kit # RM-98164-7
  • I spoke to my contact at Roadmaster who told me that the 7-Wire to 4-Wire straight cord kit, # RM-98164-7, is 6-1/2 feet or 78 inches long. If you need even more length I recommend the Flexo-Coil kit, # RM-164-7 which is 8 feet or 96 inches long when stretched out.

  • Recommended Blue Ox Equipment Needed to Flat Tow 2011 Chevy Equinox LTZ Behind Tiffin Allegro RV
  • According to my research, the 2011 Equinox LTZ is capable of being flat towed, but I suggest you consult your owners manual and confirm this for yourself. To flat tow the vehicle, you will need base plates, a tow bar, safety cables, a wiring solution so the vehicle taillights work with those of the coach and a supplemental braking system. For the base plates and tow bar, I would recommend the Blue Ox # BX1689 and the Blue Ox Alpha tow bar, part # BX7365. The tow bar includes safety...

  • Converting 7-Way on Motorhome to Roadmaster Diode Kit 4-Pole on Flat Towed 2012 Ford F150
  • To convert the 7-way on your motorhome to work with the 4-pole plug of the Roadmaster Diode Kit you referenced, you have a couple of options. You could use an adapter like # PK12716 that would plug into the 7-way on your motorhome. You could then plug the umbilical from the towed vehicle into the adapter. This would be a good option if you were not planning on towing frequently. Another option would be to remove the 4-pole flat connector on the truck, and replace it with a 4-pin...

  • Roadmaster InvisiBrake # RM-8700 Used w/ TrailerMate Wiring # TM781124 on 2015 Wrangler Unlimited
  • Yes, the Roadmaster InvisiBrake Supplemental Braking System, # RM-8700, on 2015 Jeep Wrangler Unlimited. You will need the Hopkins Tail Light Wiring Kit, # HM56200. This harness would not require the use of diodes when using the InvisiBrake system. As for a coiled 7-way, I recommend going with the RoadMaster 7-Wire to 4-Wire Flexo-Coil Kit, # RM-164-7. For this you would just cut off the 4-way flat connector to be able to wire the new 4-way round connector and you are ready to go.

  • Additional Wiring Parts Needed to Flat Tow a 2012 Jeep Liberty Behind a RV
  • Once you install the Roadmaster Bulb and Socket Wiring Kit, # RM-155, on your 2012 Jeep Liberty, you will want to determine what type of trailer connector socket is on your RV. If your RV has a 4-way flat connector, then you can install a 4-way trailer end connector like part # 18004. If your RV has a 7-way connector, then you could install a 7-way to 4-way wiring kit like part # RM-164-7. This allows you to install a 4-way socket on your Jeep and includes a Flexo-Coil cord to connect...

  • How to Change Out 4-Way at Rear of Motorhome to Work with 7-Way on Trailer
  • Thank you for the pictures! What you may be able to do is install the Hopkins # HM47210 on your motorhome to replace your current 4-Way round connector. I'm guessing the 2 wires for your brake controller system are for 12V power and for the brake controller signal. If this is the case then you will need to connect the following functions on your motorhome wiring with the following wires from the Hopkins connector: White - Ground Yellow - Left Stop/Turn Green - Right Stop/Turn Brown...

  • Wiring my 1997 Jeep Wrangler lights to work off my motorhome wiring
  • Your Jeep does not have turn signal lights separate from the brake lights so you will not need the RM-732, Roadmaster Brite-Lite Wiring Converter. Your RV already has the 4 and 7 pole connectors wired so the RV already has a converter if it was needed to install the trailer wiring so your wiring to the Jeep should be very straight forward. I have posted a link to our wiring page and to our tow-bar electrical page for you. You may want to consider a Roadmaster 7-Wire to 4-Wire Flexo-Coil...

  • Is 10 Ft Flex Coil 7-Way Round To 4-Way Flat Adapter Cord Available
  • The closest to a 10 ft coiled 4-way to 7-way round adapter cord we carry is the 8 ft long RoadMaster 7-Wire to 4-Wire Flexo-Coil Kit, part # RM-164-7. This water, oil, and chemical-resistant cord can extend to more than 8 ft and then conveniently contract for easy storage. We do not offer any 4-way to 7-way adapter coiled cords that are 10 ft long or longer. Please note that Flexo-Coil cords are not intended for use with RoadMaster All Terrain tow bars, or any other tow bar that...

  • Wiring Extension for Use with a Roadmaster Sterling Tow Bar
  • For your Sterling tow bar I recommend Roadmaster extension # RM-98164-7. It is a straight cable with the 4-Way unattached so you can route the wire through the guides on the Sterling tow bar. With an extension like # RM-164-7 you would need to wrap it around the tow bar arm instead of using the guide channels on the Sterling tow bar.

I attached an install video for you to check out as well.

  • Do the Turn/Brake Signals on the Wiring Kit # BX88267 Need to be Separated for a 2004 Mini Cooper
  • I am a little bit confused as to what you are wanting to do. The Blue Ox Tail Light Wiring Kit # BX88267 that you mentioned uses its own bulb that works both as the brake and turning signals. It completely bypasses the wiring on your 2004 Mini Cooper and directly connects to the motorhome for signal source. If you check out the linked installation video you can see our team install this kit as well as the Flexo-Coil Kit # RM-164-7 for flat towed wiring.

  • Flat Towing Wiring Harness Options for 2012 Fiat 500
  • There are two ways you could wire your Fiat 500 for flat towing. In scenario # 1, you could use a 4 diode kit like # RM-15247 which would use your tail lights as stop/turn/brake lamps. Your lights would work normally when actually driving the Fiat, but when you're flat towing, you'd only use the red bulb on the back of the Fiat for all the taillight functions. Scenario # 2, if you wanted the taillights on the Fiat to operate 'normally', that is to have the turn signals use the amber...
