Did some digging after work today. Pulled out the ECM. It is an Accel Electronic Control Module.

I can find no data or info on the WWW for it. Of course it's 23 years old so that isn't surprising...
It also appears to have a matching wiring harness with call outs printed on the wire.

The back of the box has a serial number and Spark/Fuel Management on the sticker

The question I have is:
Does this box have Electronic Trans Control?
Probably not, no mention is made on the sticker of shift control. So what did they do with the 4L60E? Swap in a 700R4?
I am taking the van out to my buddies shop tomorrow so we will put it on the hoist and see what we have.
ANY insight on this early FI Controller would be appreciated!
