Steve ( a member here ) has a really good listing on his
site
One way I've found to be sure the right ecu is in the right case is to pull the cover and match the number on the white harness connector inside to the number printed on the indefication tag on the cover.
The last 4 digits should match.
In your case it should read
E2T36574 on the tag, and
6574 on the connector inside the ecu.
A bonus would be if it had an "e" at the end.
"e" is for e-prom /ubbthreads/images/graemlins/smile.gif
If it's there, it should be a 931 coded chip.
