These are the BLUE & RED PCM connector pinouts that will cover 1999-2002 F-Body ONLY . Your harness MAY NOT have a pin in a location I have listed
having a wire. I have tried to list all possible wires that will show up
99-02. If I show a wire, and your harness does not have it, you probably
don't need it anyway. You can use this info for a Corvette harness, should be very close, pay attention to location of 5v references and ground references.
Corvette will also have some extra wires for drive by wire stuff, and won't have
throttle position sensor.
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, and EGR, then you will not want to remove those components.
Any wire NOT highlighted does not get touched, its required for proper
engine/transmission control.
When you are removing wires from the harness, for instance pin 70 of blue
connector, oil level switch. This brown wire will lead you to a connector
that will have another wire on it. This other wire can be removed as well.
In this instance, it will be a black wire, that will go to a ground splice.
Simply snip this black wire from the ground splice, and you can remove the
connector with its two wires together. Same rules apply to other
connectors you will get to that may have other wires once you get to it, rear
oxygen sensors when you remove the two wires from the PCM, you will have a PINK
and BLACK remaining, those two are again, traced back to their origin, and
removed.
