Well, I've torn everything out of the console, unplugged fuses, disconnected the battery... nothing. I know which harness gives power to the tilt, but I'd love to know which wire-- I'll just snip it. As of now, I have to keep the button taped in the pressed position. If that works ok, I'll just glue it.
Ebay sells alot of these touch screen/computers, but not sure what kind of hassle that would be: installing would be easy, but the chip and other electronic watzits might not register with the car. I don't know. Working on a damned transmission is tons easier than dealing with electronic stuff.
