7-way Oops

So, this happened on our last drive. Not exactly sure how, but guessing it got caught in the hitch somehow...


Thinking about how to fix it, I was thinking just to buy a new cable and connect it it, but it disappears into the frame on the inside just under the propane tanks. Any idea where it goes from there?


Does anyone have any thoughts on whether I should...
- Replace it entirely all the way back to wherever the cable goes.
- Cut off the plug and rewire a new one on the same cable
- Install a junction box (like this) where I've shown the green box below.

I like the idea of adding an aux cutoff that cuts off the 12V power when the lights are not on (so we don't drain the truck battery charging our lithium batteries when parked - already did that once!), so figure I could do that in a junction box, or at the location the wire feeds to, if I can find it...

My vote is to replace just the plug.

The 12V line from the 7 way terminates in the DC distribution box, its location will vary by floor plan.

This also may help...POI I now use a Velcro strap instead of the zip tie.

I'd replace the plug (X3). This link about how your trailer is wired might provide greater comprehension regarding the work involved in a re-wire decision.

I agree with multiple other posts, replacing the plug seems like your best path forward. Damage is so close to the plug that length may not be impacted, and you might even have a little “slack” of cable in your path (I had some). If no slack, and length is tight after repair, there are multiple options for a pre-made 7 way extension, if you really needed that. I think pro pride even sells one but you have many options to fill that need if it came to that. New plug (only) approach sure seems like much less work (and less frustration) that trying to replace the whole harness.

NickA,

If plan A don’t work and plan B is cable R&R I might have a few tips. I just did a full plug to junction box cable on my 2007 Classic.

Models might have variants but I might save some grief on cable job.

For what it’s worth, I installed that junction box you linked. I removed the propane tray and installed inside the a frame. Is super straight forward and will make replacing the cord easy in the future

Replace it back to the box. Rip out the vulkem black caulk in those holes when done. It goes into the frame and them back out just inside where the a frame disappears under the trailer then up through the floor.

With a HAHA or PP hitch, get a longer cord, like 12’. Get a cold weather one so it will be flexible. I don’t like the extra connections of a pigtail because it is another point of failure. Not hard to rewire. 3 lines go to the DC dist box and 4 go to the turn, brake, reverse lights directly in my 2019 Classic. There may be.a plug to make a quick connect for the DC box wires. Had pull that pigtail off from out of the box because I couldn’t find a replacement for the 7way cord plug.

Fewer connections and splices always seem safer and more reliable to me. Plus, I like to wire things.

That's some been there done that type of advice and less connections, good stuff.

FWIW my Classic took all 11' of cable.

I use the same pin. It serves many purposes, it keeps the 7 way centered, it keeps the 7-way off the ground or getting caught, and it also locks the coupler!
