Flex Coil Adapters provide increased durability and the additional length that may be necessary to reach between the tow vehicle's socket and the trailer/towed vehicle's plug.

In addition, Flex-Coil Adapters with Nite Glow illuminate on activation of the tail light function. This enables the user to find the electrical connection in the dark and shows that the vehicle's trailer wiring system is working properly.

Great when pulling your vehicle with a tow bar, this 6 pole round extension has connectors that light up, making it easy to hook-up your vehicle at night. Coiled design keeps wires from dragging on the ground.


Sturdy cable that's worked great for it's intended purpose. The cable seems a little short at first, but extended fine in spited of my dropdown extension that adds another foot between the motorhome and towed vehicle. The soft flexible connectors concerned me, but have never failed & turned out to be a blessing, as I needed a little give to fit around the tow-bar's crossmember. Overall very happy with the purchase.

A year later and my initial evaluation still stands. If it fails now, I would likely get another.

Weather has been unkind to my previous connection cord between my motorhome and my TOAD, with the covering peeling back in several places. Maybe I should not leave it out when not in use? I promptly got the new cord when ordered from etrailer and it looks great - adding to my peace of mind as getting ready to head to Florida on Dec 26th.

This extension adapter does have weartherproof jacketing over the wiring for protection. You can use part # CG74VR

Worked fine. Thanks - David


It work's and show up in great time less than 2 days


Excellent so far and appears to be well constructed. Have used with a Blue Ox Tow Bar.

Worked great while we had the Motorhome but unfortunately had a major Diesel engine problem on way to California last June and cost of a reman engine was not worth the investment in an older RV. So had to sell unit as e in Utah and barely covered our costs of getting back home. But unfortunate things happen and it could have been worse. We had many years of great experiences traveling around the country but mostly in our older but nicely maintained 1992 Pace Arro

I needed to replace an older 6 pin round cord. I had started looking in March in Texas,on my way back to the Midwest. Along the route I called multiple trailer and RV outlets. Everyone had suggestions for " jerryrigging " something by buying more connecting devices. Back home no luck until I found etrailer and there was what I needed. The price for a new cable was less than the contraptions others had suggested. the cord is excellent, it arrived promptly and actually looks exactly as pictured. I could not be more pleased


Still using this product. Works well. Light the light in the plug letting you know it is hot/working.

Still working as it should.

I will look forward to using the coiled extension to supply lights to my tow vehicle from my RV. Previous one I had just wore out and I found this model. It looks the same except for the nite glow feature. I will update review after putting the extension into service.

Used it briefly and it is doing good. Health issues have kept us from being on the road as much as we would have liked.

I bought one of these in another brand I think in 2005. It lost its springy many years ago. The outer coating got rotted away so I've repaired it many times by wrapping it in electrical tape but it still worked. The ends on it were metal. I'm happy to have received this one that has springy.


No problems at all. The springing action of the coil makes it easy to position the cable away from the moving parts of the hitch.


I had a difficult time finding a 6 round to 6 round connector for our old motor home to tow vehicle and did not want to change connectors. I found just what I needed from at the best price on the internet. Thanks.


I received my 6 way cable to connect my 04 Dolphin RV to my 98 Jeep TJ .Shipping was very fast with excellent tracking information .Price was also very competitive.It works great !! Thanks etrailer !!


This is a wonderful connection. Work at 100% at 50% of the price of other makes. Well constructed, love the indicator lights on each plug to indicate connections. Sturdy coil, easy to see and firm. If I ever need a replacement shall one quickly. Products arrived quickly and at an affordable price.


Cord arrived on time as promised. So far it works great, a lot better then my old metal ended one that I kept having wiring problems with and would come unplugged if I didn't wrap tape around it to hold it in.


Product was shipped quickly and arrived at the designated time. It plugs into my RV and toadie fine. I couldn't check to make sure it works due to where the RV is parked. ETrailer is a good company to buy from. Very reasonable prices and shipping costs


This is my 1st order with etrailer. Am I ever glad that I found them! Ordered on a Sunday, loaded the same day! Tommy was extremely helpful. Outstanding overall!


Sporty looking cable delivered quickly. Molded plastic ends appear to address issue of pieces coming apart on my old metal over plastic end cable. Once the special little screw falls out or pulls out of the plastic there's no good way to hold it together.
Although I have not used it yet, the molded plastic cord ends appear to address my issue, and it's sporty looking to boot!


The trailer coiled extension was delivered in a short time from ordering. etrailer staff kept me informed of the availability of the product and when it was shipped. I am very pleased with all the items I have ordered over the past six months from etrailer.


It's been a year and we traveled cross country over 7 months with no issues! Love that it lights up!


Good company, good products. Will continue to buy from etrailer


This company is my “go to” for parts for my Motorhome. The staff is very patient and helpful, the product is fairly priced and delivered as promised or sooner. Great service!


exactly what I needed, good quality and fast shipping, couldn't be happier with etrailer


Exactly what I order and received it in a timely manner. Works like a charm. Perfect length for towing behind Motorhome.


High visibility yellow is not only functional but looks cool as well. The lighted ends are neat. Other than that it's a cable and does the job of connecting RV to the toad.


Product was as advertised. Same as available locally in store, but at 40% lower price. Delivered on time. Great deal.

Really nice heavy-duty cable. Delivered on-time at a very reasonable price.
