I decided that since my car would be off the road for a month or two as I work on the engine, it would be a great chance to do a custom wiring harness for the car. This would mean the body and engine/ECU wiring harnesses would be separated and independent of each other. Try to keep it all as simple as possible, will be especially nice to have a dedicated harness for the Megasquirt =)
So I was lucky enough to pickup an entire wiring harness (body, main, power, dash) for a decent price and got started working on it.
I've stripped the following from the harness so far:
- All engine wiring
- Air Flow Meter
- Ignitors & coils (going COPs for the Megasquirt)
- IAC valve
- Purge valve
- O2 (going dedicated wideband)
- AC stuff
- Clutch switch
- Neutral switch
- Fan switch (Megasquirt will control fans)
- probable more... can't remember
All engine/ECU related fuses and relays will be kept separate and located close to the ECU. The engine bay fuse/relay box will be made redundant and relocated under the dash as there will only be four fuses used at that location.
