94 mx3

wait, why do you have to swap the dash harness?

Because in 94 mx3 they did something weird with the wiring so u have to swap out the harness.

Depending what month your car was built will dictate if it is obd1 or obd2. if it is obd1, you can use your stock harness and you just need one wire hooked up for the VRIS. if it is obd2, swap out the engine harness and put in the bp harness and ecu and there are threads to show which wires have to be swapped in the bp harness to work right. pm me and I will help too.

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...

Actually, for some reason, Mazda released both obd1 and obd2 cars in 94.

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.
