thanks for the info to begin with but I am trying to figure out which module is which. The PCM is which one? is it the main big box module (about the size of a cigar box) located on the drivers side wheel well next to the underhood fuse box. also, what is green/black leakage of current. I'm more of a old airplane mechanic so i'm learning my way around here on 4 wheels. Also is the VCM and the PCM the same thing diff names???
