These are the RED & BLUE PCM connector pinouts that will cover 1999 to
2002 4.8/5.3/6.0. 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. SOME LOCATIONS HAVE MULTIPLE POSSIBILITIES DEPENDING ON
WHERE VEHICLE WAS BUILT, MOSTLY DEALING WITH O2 SENSORS. EACH POSSIBILITY
WILL HAVE ITS OWN LINE. For more info about the o2 sensor differences click
here.
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.
I have been asked to identify the wires for electronic auto trans controls
that can be removed if you are not going to use electronic automatic
transmission. Here they are, the Pin# will be highlighted in
RED. If removing trans, pay
attention to BLUE connector pin 41. Some harnesses are different based on
type of o2 sensors you have. Some this pin goes to trans only, some
harnesses, there is a splice, and this pin goes to coolant temp sensor AND
transmission. Simply cut the wire to the trans AT THE splice if this is
the case.
WIRES THAT ARE NOT HIGHLIGHTED REMAIN UN TOUCHED.
THEY WILL GO DIRECTLY FROM PCM TO A PLUG, (SENSOR, SWITCH, DEVICE ETC.)
