Working on 86 rx7 that has 91 gtu motor and ECU. The 87 had no ecu. 87 Wire plug that goes to the right side of ecu won't fit. does anybody know if they sale converting plug or if anyone has a wire diagram showing plug for 87 & 91.
ECU has to match with engine and tranny. Why don't you go with EMS which eliminate the prob. Secondly I sure wouldn't want to use them 20+ year old harnesses if I can help it.
