Has any one used the original wiring out of a camaro/fire-turd with a tpi setup?? Modified of course. So all you use is the stuff you need. See this is my version of the budget beater, (trying to keep it as cheap as possible.) A buddy gave me everything for the tpi conversion except, 5.7 fuel injectors, presure line from tank/sending unit/fuelpump to engine, and wiring.
