These are the BLUE & GREEN PCM connector pinouts that will cover 2004
GTO ONLY .
BLOCKS
HIGHLIGHTED LIKE THIS, ARE WIRES THAT ARE NEEDED, AND GO TO EXTERNAL CONNECTION
FOR STAND ALONE
BLOCKS
HIGHLIGHTED LIKE THIS, ARE WIRES THAT CAN BE REMOVED FROM PCM CONNECTORS, NOT
NEEDED.
Note: Removing all of
these will
result in a non-emissions friendly harness. If requirements are for 4
oxygen sensors, EVAP system, then you will not want to remove those components.
Any wire NOT highlighted does not get touched, its required for proper
engine/transmission control.
