E-21 Wiring Harness
 

I am wondering if anyone out there has replaced a complete wiring harness on an E-21? Mine has developed several strange habits and I am considering rewiring the entire car. From what I am reading I am probably asking for all kinds of fun but, I am beginning to think the amount of time I am spending with a VOM tracking down faults in a 30 year old system could possibly be better spent just redoing the whole thing......any thoughts?:videogame
