So when I bought the car I new it was gonna need some work...I did pay 900 for it...anyway I have an 87 740 Turbo Wagon. It runs well actually with just shy of 203k on it...Ive replaced a few things here and there, and have been avoiding the birds nest of wires sitting on the driver's side of the engine. Well I was under there today I was moving some things around the amazing wiring work by the previous owner was faulty at best...anyway I'm planning on replacing either they bird's nest of faulty wire or was wondering how involved just replacing the entire wiring harness was...has anyone done? and how much work am I looking at.
