12210553 is the GM #.

Thanks--Is that the part# or the # from the pcm itself?? I want to try a pcm from an early model Ecotec--I can not get my PCM to release its hold on my fuel system.

No that's the GM part # in the parts catalog.

Thanks too, I needed that for my ecotec swap. Is a 2002-04 Cavalier PCM the same p/n? My ecotec is a 2004, but I have an 02 cavalier.

Can you also give p/n for the engine wiring harness for 2002-04 cavalier ecotec 5spd, w/abs? If they are the same through those years. If not just the 2002 cavalier. PLEASE.

I cant look up any GM parts other than Saturn

Hey I got a 02 cavy ecotec as well but mine is a auto , so I can go to the dealership and ask for that part number for my pcm?

NO. They are different for auto and manual transmissions.

The PCM controls the function of the auto tranmission, whereas the PCM for manual has nothing to do with the transmission.
