And they make smirks cause we don't give a crap about typing. YOU THE MAN!!!!

Can anyone spell it out in dummy form for the 1990.

Or email me instructions toddcod@yahoo.com

Thanks.

 

This diagram should help, except you need to find a switched +12v wire to the ECU, which shouldn't be too big a problem.

1990 - 1995 Mazda Miata ECU Diagram

From what I remember:

Get power and ground to the appropriate wires on the pill box. Hook up the o2 signal wire (from the sensor) to the input terminal on the pressure switch and the NC terminal (to the ECU) and the output from the pill box to the NO terminal. Run the vacuum line and you're set. If that doesn't work, switch the wires on the NC and NO terminals.

 

glad to help you out.

 

Drive safe
