I've got a 1991 Pontiac Firebird 305 TBI. I've found great prices throughouth the internet on different parts for the conversion to TPI. Below is a list of the parts that I have and how much they cost... The only item I am lacking is a wiring harness for the TPI. If any of you have anything, please let me know... I don't want to spend several hundred dollars on this one measly item ( I know it's not really measly since it is the only thing holding me back...) My only other option is to take my TBI harness and convert it over myself. I realize I could've bought the whole kit for $550.00 but I've been accumulating these parts over a good period of time (budget constraints).
Any help would be appreciated.
TIA, Braggs
