I picked up a Jetronic from an '87 at the junk yard for scrap. I just
wanted to see what's inside. I broke the little white extra board with
the rom on it getting it appart. Looking at the chips and many, many
other small resistors and capacitors, I'd say this thing is mostly
analog. it only has four T220s and one of them is for the power
supply.

I think you need a GM computer (or '332), GM sensors, and a GM harness.

Good Luck.
