    Looking at the V8 conversion thread it states the PCM's are the same. However, the PCM out of my '99 V6 is gm# 16263494 and the connectors are totally different then on the '02 harness I bought. I've seen mention of a '12200411' PCM. Is the 411 the one I should be using? If so, is ebay my best source? Wonder if Nelson would take mine as a core.. lol.

    Just pay for your core, probably would be the same as buying one on ebay and having it shipped
