I don't have exactly what you are asking for. But, I have a wiring file for putting the 12200411 Gen3 type PCM into an OBS 98 truck with the Black Box PCM. It probably has the info you are looking for. PM me your E-mail address if interested; and I will send you an EXCEL copy.

I'll try to scan the pinouts tomorrow and post them. Here's the 96-97 in pdf. that will get you started but the 98 has a few minor differences.
