Below are the PCM Connector pinouts specifically for a 2004 Pickup with BLUE and GREEN connectors.  These pinouts should be similar to 2003-2007 PCMs with the BLUE & GREEN connectors.  2006+ harnesses may have fewer wires, these are not needed anyway for stand alone swap.

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.

WIRES THAT ARE NOT HIGHLIGHTED REMAIN UN TOUCHED.  THEY WILL GO DIRECTLY FROM PCM TO A PLUG, (SENSOR, SWITCH, DEVICE ETC.)
