Replacement 7 pin umbilical cord

[jackanddiane]

Greetings! Need some advice on where to find quality replacement 7 pin umbilical cord for our 2013 27 fb. Are the wire configurations the same on most replacements? Any advice on snarking cord thru frame?Thanks

My .02$

Pollak flat blade plug.

7 wire cable is pretty easy to find. I got some at NAPA Belden brand. Nice stuff.

Disconnect batteries.

Take pics of 7 way junction box wiring color codes.

After removing cable but before pulling it out secure a nice strong cord to cable end. Now snake wire out and cord will follow path. Attach cord end to new cable and use to recreate cable path. Make your connections. Connect batts and check all circuits.

Is your plug damaged or the cable? Plug only replacement is viable repair.

Thanks Gary- Cable has been repaired twice already Thought a new one would be smart before heading back to AZ from Ct.

I know a pre moulded cable and plug exists. But if it’s a Bargman you get the V shaped connection in the plug that IMHO has been over reported as a marginal connection.

I’ve had a replacement Pollak flat blade plug for quite a while. Connect, check lights and drive.

When I replaced my 7 way cable, I found one on amazon that came with a small weather proof junction box. I drilled, tapped, and mounted the junction box to the A-frame under the propane tanks. It was all color coded the same as the cable that was there.

I can’t recommend a specific replacement, but there are three things you need to consider when purchasing a replacement:
- Length: long enough to go from your tow vehicle to junction points inside trailer with some slack.
- Electrical connectors: there are two types; blade (most common) and round. Make sure the one you purchase mates with the type on your tow vehicle.
- Wire gauge: minimum 10 gauge for power and ground wires, 12 gauge for brake wire, 14 gauge for remaining wires. Remember, the lower the number, the thicker the wire.

I pinched my umbilical twice making tight turns. Cable was too long after losing my Hensley. I inquired at the Airstream dealership in Lake City Fla about connecting inside or putting a junction box outside. My connections inside the trailer were partially buried in the walls. They recommended putting a JB under the front of the trailer right where the cord went up inside the floor. On mine there was a cavity inside the front cross channel. Makes life a lot easier
I found a plastic JB at Home Depot
