The one I have in my basement will work for you.

The 94+ MX-3 RS was the only one with that exact motor.

[gxser]

Rule #1 of Pick'n'Pull's is never trust the employees to know ANYTHING specific about cars.

Seriously, trust us.

i found a parts car a 94!! i wonder if i changed the whole harness if it would work on my 96? did they change much between these years if anyone knows thanks in advance....

[Ryan]

Yes, 94 was a bastard child, and OBDII started in 95.

[gxser]

ok so ii got the harness and ecu from a 96 but my ecu has diferent code on it mine SAYS remanufactured B6GD and this one is just B6GD i put that in with the harness , but now the freakin thing wont start it turns over fine but i have no spark. the fuel pump will not kick in.. and my engine light will not turn on .. i had the similar problem before it was the engine fuse .. i changed the ignition switch. i have no idea what to do now any help would be great thanks in advance

[Ryan]

Dear lord. I remember this.

Poor guy, thats a horrible mess.

So you put a new 96 harness into the 96 car with a 96 ECM, and no go?


No fuel pump kickining in means that you're not getting the signals from the disty. Check between your harnesses that the distributor pins are correct, that is, each pin on the disty harness traces back to the same pin on the ECM between the harnesses.... follow?

Aside from that, if your new harness is indeed good, its just a matter of tracing it all back... start with looking for 12v and ground at the disty.

Did you ground the ECM properly? This is important, or you might cook it.
