New Wiring Harness...

[rustang girl]

I took my car to the shop no more than a month ago, there was a short somewhere. Got a few wires under the dash and a few in the front fixed. Then when I got home I replaced my alternator. It's a pain in the butt to tension it. Then I replaced the, errr forgot the name of it. Little power box on the drivers side, next to the radiator. It worked for a few days and then I got a short again, dead battery. Got the battery checked, it was good, it's new. So I took it back to the shop, cuz of the short it broke the new box thingy I bought, shorted it out, and Mike (mechanic) told me the alternator would have been next. So, he fixed some more wires and it worked fine for about a month. I was out of town visiting friends for what was supposed to be a weekend, turned into a horrible, unwanted 2 week vacation, and paied some idiot $65 for a new wire attachment, and it was still broken. Finally said screw it and drove it home how it was. As long as I didn't/don't shut the car off for an extended period of time, it's fine, otherwise I unplug the battery. On the way home it overheated, and I blew a head gasket. Mike has it now, at the shop here in LA. I won't get it back till Thursday, soonest. I hope this will stop the shorts, but I know it won't. What I need to do is replace the wires. And now to the point of all of this rambling, does anyone know where I can get wireing harnesses for a 1966 Mustang, coupe? What do you suggest I do?

Thanks a lot ahead of time, for any assistance.
