New 7 way cable (umbilical cord)

[rbs]

Need to install a new 7 way cable on our 04 25' Classic, as the original suffered a significant pinch and I would like to replace. The original cable is sufficient length to accomodate a ProPride hitch, so I would like to find out how long the original cable is. It appears that the cable is routed to a black box located in the box under the sofa that houses the charger/converter. I assme all of the connections are made there. Also, what method is used to fish the new cable thru the frame into the trailer? Any and all help appreciated.
Thanks,
Rod

I too have the Propride.

Fishing a new cable is problematic as the old one is clamped in place with clamps that are difficult to reach without a good deal of disassembly.

Here's what I did, which solves the pinch problem, eliminates the need to fish new cable, and allows you to carry a spare for the next time something happens;

It is a lot easier to just get a waterproof 4 in. electrical box and cover and cut the old cord long enough to make a connection to the new cable on the side of the frame. Make an easy point to do future testing on the plug for short and open without having to remove the plug from it's sheath.

Thought I would send a picture.

Etrailer.com has several boxes that might work for you. You can also my 7 conductor wire from them by the foot. I have ordered from them many times and get great service.

I like your setup, especially the spring to keep the cable out of harm's way. Is the spring a specialty item or available at Ace?

Thanks to everyone for responding

I got it at the local NAPA. I asked the counter guy to show me the springs truckers use to hold up air lines for their semis. Those were too big but I found something that would work in the same area in back. I added the little chain, bracket, and split-ring connector from stuff I had around the shop to provide an easy means of disconnection. I have another complete cable assembly (including spring) in the bottom of my shore power compartment for use in the event something happens to the usual one.

I have decided to use the junction box method, opposed to running an entire new 7 Way cable. The Airstream wiring diagram shows the 7 Way uses an 8 gauge ground (white) and I am not having much luck locating one. Anyone know where I could purchase the correct 7 Way cable?
