harness fire...

The cheap plastic insulation in ALL vehicles has a tendency to melt and weld other wires in the harness to adjacent wires. It can make a mess. I recomment you inspect the harnesses carefully, untape them if necessary to be sure there are none of this.

Old Mopars are TERRIBLY underfused. By that I mean "not well enough protected."

In my younger days, a young lady mashed up my 70 RR While it was in the shop, I had a loaner car that suffered a dead short in the alternator. I sat right there and watched the under-hood harness go psslsllfffffssssfffftttt!!! and then blow the fuse link.

Called the dealer. Said "send a wrecker, and another loaner car."

So they sent a pickup truck with a set of booster cables. Driver says "we're gonna need a tow truck and another loaner car!!"
