Part number is the best way. If you have it, post the part number of the ECU you are planning on getting.

Not sure why this old thread got bumped, but I may as well add some info. My 89+ Gray Plug JDM A/T ECU is part number 89661-14230. Gray Plug M/T should be 89661-14630. The sticker is purple & red on the JDM instead of blue & yellow on the USDM.
