I had an 86 IROC. I pulled the computer, harness, and TPI system out and put it on my 350. Two websites helped me a lot:
www.jagsthatrun.com
www.chevythunder.com
I used the existing harness, but cut all the stuff off I didn't need. The Helms manual for the 86 IROC helped a TON on this part. The manual was about $70 but was well worth it. I learned a lot about the TPI system from that manual.
Since I was going from a 305 to a 350 I bought bigger injectors. I also had my chip reburned by Brian at www.tpichips.com. I told him what I was running, and he made the chip work for me.
There are a ton of threads on the board on TPI. Do a search. TPI may be a bit short for a search though, I will try a google search and see what I can scare up for you.
