Wanted: TPI Engine Wiring Harness - TPI Parts List.xls (0/1)

Nov 25, 2003 2 Replies

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. The excel sheet included is a list of the parts that I have, where I got them 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.



Any help would be appreciated.



TIA, Braggs

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.
