Coiled Wiring Connector

I am considering changing the seven pin cable on my trailer to a coiled one from etrailer. I had a coiled setup on my toad when I had a motorhome, and it worked well, but not sure if a coiled setup is the best for a trailer. Has anyone changed over to a coiled set up and how is it working? Since the junction box is 5.5' to the truck connector when hooked up, I guess the 8' pigtail is the one I need. Thanks for any advice.

    I am looking to change since I damaged the current one this past weekend. It looks like I pinched the wires somehow, but I'm not sure where. I think it was when I was getting gas. I came off the freeway for a gas stop and pulled into a Shell station with the worlds largest speed bump coming off the road; there was a huge hump from the road into the station, not sure of the purpose. I went super slow, and nothing dragged, but when I got to my destination and was un-hooking I noticed a pinch in the wire bundle. Also, it looks like the sway control lightly contacted the ball mount, but no damage there. Should of hit the hump at more of an angle maybe. The wire bundle was routed like it has always been, and I can't tell where it could have been pinched, so I'm guessing it was the hump that did it somehow.
    Everything still worked, so I didn't mess with it till I got home. At home, I tested everything while stressing the wires at the pinched point and everything still worked, and I split the outer sheath and all the individual wires are fine, but were obviously pinched and possibly wire strands are broken in the insulation. Since they are damaged, I'm going to change the pigtail anyway, so I'm thinking of going with the coiled setup.
    OK, that makes sense. If I was going to replace mine, I would consider the coiled cord, for sure. I replaced the brake cable with a coiled one and really like it better.
  • At least you got to upgrade part of your trailer. IMO, Coiled vs uncoiled: coiled is superior because the coil may "bounce" off a pinch point and the coil allows easy travel of the length.

    That said, I used my original umbilical's stranded wires and put them in a length of Liquidtite conduit. If the umbilical reaches the road while underway, the Liquidtite will offer a few minutes of protection. The connector may look like someone took a grinder to it but the wire may be saved.
  • I just ordered the 8' coiled replacement 7 pin, so I'll report back once I receive and install it.

    My wife mentioned the flood barrier too. Once over the hump, there was a slope down to the station building. I was only at half a tank of gas.....should have went on to the next Shell station.
  • I don't have one but I have considered it many times. I need to change my plug end anyway so I might.

    As far as that huge bump at the driveway, Maybe they had some nasty flooding in the past from a desert monsoon.

  • E.Trailer Coiled umbilical cord is good

    They also have coiled emergency brake switch cables

    Then Nothing needs to be tied up to keep from hanging/dragging



    But on the other hand......I'm cheap and don't replace perfectly good working equipment just for giggles. Got to break first. :B
  • Just curious as to why you would want to do this. Is there a problem with your existing cord?
