I have an 1989 Iroc and im converting TBI to TPI and i was wondering what are the best steps for me to set up the wireing harness, just like the TBI? and i was wonderin what else would i need, i need toe tv and throttle cable, fuel pump, and air induction, I have the whole intake setup, and sensors and computer can some let me know wat else i need and tips if they know any, it might be covered all ready and if so let me kno, ive read of the thread about the 90-92 convertion but doesnt clarify alot

 

Tech article on this website about converting from TBI to TPI is a little old now but it will give you the basics. Then you can search the boards for all the info added in the last few years. This is a popular swap and well worth the effort. There are several threads from guys who have done the swap and posted about it.

 

thanks, i will check it out
