    I just finished swapping my auto for manual in my 200gt. car runs and drives fine with the auto computer. I want to swap in a manual computer and I got one from craigslist and its was a JRX0. when I installed it just turned the fan on. I tested all grounds and computer seems to be dead. I want to purchase another one from ebay but I need to know which are compatible? or did I miss something I should do when installing a manual trans computer. dealer even tried to program JRX0 computer and they said it was dead. any help would be appreciated

    There's a difference between a "dead" PCM and a non-compatible PCM. When the cooling fan runs all the time, that's a sign of no power to the PCM or a bad PCM.

    Sounds like you have a bad Craigslist PCM.

    As far as which one is compatible, my recommendation is to get a PCM from a 2000 GT manual. I would not recommend using a 2001+ because of wiring changes.

    If you must use a PCM from a different MY, look only at the 1999.

    Search car-part.com for other sources of salvage yard PCM's in your area.
