I am personally thinking of trying to try this myself. I can solder wires without problems. It does appear to be a b**** of time with the wires. I have an Auto, but I am not sure if the wiring harness would be a problem because of this. I figure because of the gauges and temperature controls, I would need to keep the stock dash harness. Would this setup work with the 96 MX-6 ecu? Then use a OBD-I engine harness from a MX-6 for the engine. I just want everything to work right and passing emissions in Maryland. They just hook up to the computer to check and visually look under the car for the cat for emissions. So is all that is required to do is take the engine out, take apart the dash, separate the wiring harnesses (dash and engine), swap out the ecu, and hook up the engine harness?
The other question is what you are doing for your canada people regarding AC and powersteering? Are you able to use the MX-6's parts in place of the protege's?
I probably will find it hard to take off two weeks just for a engine swap (the wife wouldn't have it). That's why I am trying to figure what I could do to make this more an option vs getting another car. This topic is far from over.
