No other interior wiring.other than computer....no neutral safety switch. Dont know if you would need to reprogram if you didn't hook up the trans wiring. Howell seems pretty good about answering questions, keep asking for details.

MARKDTN & notsolo, thanks for the replies that helps.

I have heard good things about Howell harnesses, so I plan to go forward with this harness to save me some time and headache.

......I am leaning towards that I won't need any trans wiring because I don't believe the 1990 comp I have has any mechanical trans hook ups, I think the 700r4 in that truck is all mechanical. Anyone confirm that?

I didn't see why I would need a new PROM for the computer I have, since I wasn't deleting the EGR or changing transmission capabilities?
