obd1 and obd2 was changed from 95-96 hes getting a 94 so its obd1

I thought the only major issue was with the electronic speedo, and even that isn't a big deal...sigpic

As far as dash harness, you don't have to swap out the harness. I just swapped a couple wires at the clips and everything on my '95 is working fine. I used the Electrical shop manual from my local Mazda dealer and compared the electrical from the 95 mx3 to the 93 protege with the BP and just made the changes I needed to make to get it all to work properly.
