Crushed umbilical cord
We took our first long trip in our new Outback a couple weeks ago. Had only been out on weekends before this. 9 Day trip this time and had a wonderful time.
On the first day I started getting message on my truck that the trailer was no longer connected. I checked the 7 pin coard a few times and was always secure and had plenty of slack. Finally tracked down a pinched cable. I squeezed it back and that provided enough relief internally that whatever had been shorted was no longer touching.
I obviously need to get that fixed. But I'm still trying to figure out how that could have gotten pinched. Any ideas? I don't have pictures. The part that got pinched is under the propane tanks. Should I take this to the dealer for replacement or just but a new cable and do it myself?

A replacement 8' cable costs about $25. Your time to do the actual replacement is ??? Depending on the distance to your dealership, you might well find that the price of fuel to tow your trailer in for repair exceeds the price of the cable and your time.
Here's one place to purchase a replacement cable, there are many others, some probably much cheaper than this: https://www.amazon.com/Hopkins-20146...7+pin+rv+cable

Umbilical cord replacement is very much a DIY job. The junction box will be under the frame behind the leading edge of the trailer wall. Just match the colors AFTER you disconnect the battery.
There will be 7 wires, but you will only use 6. You can either cut off the unused one or insulate the end so it doesn't short anything out, IIRC its yellow.

You're right, Chuckster, the "spare" is yellow and although it's called "accessory power" in many schematics, it's normally used for back up lights, something found on very few (if any) Keysotne RV's.

Thanks for the replies. I hadn't even looked up the cost yet. I didn't expect it would only be $25. For that price it's absolutely a DIY.
I'm still scratching my head on how it would have been crushed.

I'm starting to see the B/U lights on newer larger units, but like you not keystone.

Hold it at the pinched point and swing it through its range of motion, you'll find your answer. I had a similar situation just last week. My son unhooked the 5er to borrow my truck but forgot to drop the tailgate. Fortunately he caught himself just as the cord was smashed between the tailgate and junction box, which is on the backside of the pinbox. No damage to the tailgate and the 4x4" metal junction box was only slightly tweaked, BUT... he didn't tell me about it because he thought there was no damage and he'd got away clean. When I came home I noticed I had a left brake light illuminated on the trailer with no vehicle connected, strange indeed. Of course upon inspection I found the smashed cord with bridged conductors. Fortunately it was right at the box and my cord was plenty long to just cut it back a few inches and re-strip the wires. Took about a half-hour, including straightening up the box so the cover fit properly. --- Darned kids !
