Painless wiring

I tried every company mentioned in the previous comments with no luck. I would like to simply replace all the wire in the engine bay. The stuff in the rest of the car is fine. While I know I could just buy a complete harness and use what I need, this seems way more expensive and kind of a waste. Perhaps find everything from the 3 bulkhead plugs to the headlights.?. Any ideas?

no way your gonna get new. i guess your only option is to find a good harness on a junk yard car. or take yours out and rebuild it. you can find the schematics on line.
