My engine is a '99 6 liter and it's PCM. I will have to track down the wiring for you. I used the '99 GM truck service manual wiring diagram along with the '93 Chevy truck wiring diagram manual to get the wiring schematics.
If you haven't already checked out this site, do so. It was immensely helpful in getting the wiring ironed out.
