Greetings All. I just purchased my first BMW, 1987 325i with a 5 speed. The dealer said its battery was bad and wouldn't hold a charge. Figured it was no big deal, jumped it off and I drove it home (I test drove it a couple of weeks ago). When I got home and put it in the garage where it was dark, I realized that the Instrument Panel, rear marker, and license plate lights were on. Got the wiring diagram, chased it down to the headlight switch, and realized the wiring to it was melted. Mainly the Gray/Red wire. Several others were melted from the 25 pin connector towards the instrument panel, and from the connector towards the firewall. It looks like one of the previous owners botched a splice and the electrical tape came off. Should I try to rewrap all the wires? Can I get a new harness from the connector to the instrument panel? Where's some good places to buy parts? Thanks!
