Hey Marcus,
I thought you wanted to sell the car lol! I think you're an addict, man, you just can't stop!! If the interior is the way you like it, you could try to replace just the offending wires. However, those inexpensive wiring harnesses from the rodder magazines and ebay are awfully tempting, no? There's EZ, Its-a-snap, and a few others....
...so which harness are going to purchase?
