Harness conversion
I've seen post saying it's possible to convert a TBI harness to work on a TPI. Can anyone here walk me through that? I'm converting a 1988 TBI to TPI. Donor car for TPI was an 85.

Re: Harness conversion
Check the stickys at the top of the TPI forum. There is a whole thread laid out step by step for converting the tbi harness and computer to a speed density tuned port system. Changing to a tpi computer would make more sense to me due to a better tune but to each his own.
