Try JTR. They have a conversion manual for V8's in S-10. It cover just about everything.

Moving to LT1 Tech

 

checkout the V8 Tech forum at www.s-series.org

 

I used a Helms Shop manual for my 94 motor and a Haynes repair manual for the truck wiring. I just found all the powers, grounds, inputs, outputs, and gauge wires I needed and went to town on it. Also, Shoebox has a wicked site w/ the pcm pinouts and basic wiring diagram to get you started, that is mainly what I used till I won my set of manuals off of ebay.

You might want to check out the v8 section on www.s-seriesforum.com, there are a bunch of guys that have done the swap as well as informative posts, part numbers, and fubars to look out for. I'm Hotwire on there as well.

I'm loving mine, doing a LT4 conversion as we speak.

Good luck.
