I'm down to my last three unknown wires and the FSM leaves a little to be desired.

I'll try to give description and circuit id in addition to color.

dark green. circuit #1049. PCM Class 2 serial data
Yellow. circuit #710. Class 2 serial data
yellow/black. circuit# 625. starter enable relay

One of the first 2 is for the diag port pin.

I believe the Yellow/black one(625) is for the vats and could be pulled.

dark green. circuit #1049. PCM Class 2 serial data To ODB II port pin 2
Yellow. circuit #710. Class 2 serial data To BCM for VATS (not used)
yellow/black. circuit# 625. starter enable relay From C1 Red PCM connector Pin 39 for VATS relay

Hope this helps.

Helps a lot... yanking two last wires and extending one more. Then button the harness up. Only a LOT of hours pulling it apart:homer::laughing:
