1990 TF999 computer controlled?

I searched around and didn't find anything definitive. I have a 1990 YJ with an automatic.

Now that I have both an MC 2100 and a CRT HEI, and the associated electrical changes, is my computer controlling anything? The only thing I can imagine is my trans. I'd like to pull the computer and associated wiring harnesses to clean things up.

The trans is not controlled by any computer. There are 3 or 4 wires to it for the reverse lights and neutral safety switch.

Exactly as Burnerman said. There isnt anything electrical on that trans except neutral safety and reverse lights. Delete wiring/controller as you see fit.
