Differences between 91/92 Harness?

[Treibenschnell]

What, if any, are the differences between the 91 and 92 wiring harnesses? Thanks!

From my experience, not a thing is different unless you have an automatic or power windows, or any other add ons, but barring that no difference

rich :P

My biggest concern is the connector/s to the ECU. Still no difference?

FWIW, I ran a 90 ECU in my 93 for a while. The ECU's are supposedly different (something about the FI system), but the 90 worked flawlessly. 91-92 shouldn't be a problem to mix/match stuff like ECU's.

All the 1.6's should be just about the same with exceptions for cruise control, power windows, and other options...

The same goes for the 1.8s... Yes, there are some minor differences in the injector parts of the harnesses from what we saw with Evilspeeder's issues.

The earlier Miata's used a different injection system (as far as how the computer controls injection). I'll see if I can find a link to the place where I read that.
