I am putting a TBI 350 into my jeep buggy. It is green stickered, so I don't have any smog issues. The motor is from a 89 or 90 2500 Chevy 2WD with an automatic. I have an SM-465.
My question is who do I want/need to go to to get a new wiring harness that is clean and simple, and I need the computer flashed also, (For the no smog and four speed manual, don't I?) Tried searching I must just suck at it.

I have a gm ecm on my 258 in my cj that was from a 4.3 with an auto. You don't need to get it flashed to get rid of the automatic. You can make your own harness inexpensively, just need the wiring harness and an ecm. CHeck out the link to my tbi writeup in my sig. It will give you all teh info to make the harness and put it on your engine. My application is for my cj but since it this system came on 350's you should have an easier time.
