Can someone tell me what the major differences are between a 2000 LS1 from a Firebird and a 2004 LS1 GTO as far as the PCM pin outs and or wire schematic? I have searched but did not find what i was looking for so i need a little help.

Thanks

2000 LS1 uses a RED/BLUE PCM while the GTO uses a GREEN/BLUE PCM. Major differences in wiring will be some extra grounds and Pulse Width Modulated O2 Sensor Heaters in the Green/Blue PCM.

Cool thanks, anything else you can think of let me know. A couple of grounds and O2 wires shoudn't be to big of a deal.
