billha is on a distinguished road

This is a basic question, but can anyone tell me what needs to be done to access/remove the ECM in a '92 or a '93 SSEi? I'd like to check to see the PROM version, and I looked for it on the passenger side once and found more than 1 metal box there and couldn't even tell which one was the ECM.

It just clips into this plastic tray up under there, exactly where jr's3800 is describing. Shouldnt be to hard. Pull forward on the bottom and then pull it striaght down.
