Hi guys, I have been contemplating doing an engine swap in my car as a DIY. I've never done one before but the car is just a track car so time isn't an issue. The car has a 6A12 MIVEC in it and has the fusebox from an FTO (both under the dash and in the engine bay). It also has the climate control system installed. I would want either a CM5A or a Evo V/VI swap, both of which have their pros and cons for me, one of which is procurement. Either way though before I make any purchases I would like to know what would be involved in the wiring department. I understand there is an engine loom that goes through the firewall and into the ECU. 1. What other looms are there in the engine bay and interior that would need changing? 2. Since the fuseboxes are from an FTO and all the fuses for power windows, lights, AC, heater etc etc are in these fuseboxes, does that mean these need to be replaced or could I just "plug in" the engine loom and leave the rest as is? 3. If the FTO wiring needs to be taken out, how easy/hard is it to integrate the CM5A or Evo harnesses (excluding engine harness) to standard Lancer harnesses? 4. Are there any other considerations needed when dealing with the harnesses? Please keep answers for the electrical side of things only here, I am doing separate research for the mechanical issues.
