In the rush to get the car running in early September, I didn't get around to hooking up some of the "nice-to-haves", or so I called them. Finally hooked up the signal to the PCM for the brake status (12v + = brake "off"), discovered the '86 cruise control switch already did that. Spliced it into the PCM line, TCC lock-up is much better now.

Still need to hook up the Cable X box to get the speedometer working, SES (MIL) light, and OBD II port. Should get to those this week.

The MIL should clue you into alot of your issues. Trouble codes for OBDIIs are pretty specific

Tonight, hopefully. If the light is on, I'll retrieve the codes.
