90 and 92 ECM wiring

The ECM in my 1990 STE (non-turbo) is going bad. A friend gave me an ECM from a 1992 SE (same engine, same tranny).

Is the ECM wiring the SAME, or can someone get me the wiring diagrams so that I can check for myself?

I know that 1993 is different, but I have a 1988 book, and a 1993 book, so I can't compare.

Thanks.

Get me the OEM service number off both ecm's. As long as they match, or one supercedes the other (I can tell you if they do if the #'s are different), all you have to do is swap the e-prom from your original to the "new" one and you should be set.

I want to use the 92 eprom as well. I have been able to trace my surging problem to either the ECM, or the EPROM, so I am just going to replace both.

I will get the numbers this afternoon, or tomorrow.
