I think I posted this on the old board, but I think we were in the process of converting. Anyways I have a access to a Tpi system wiring harness sensors everything from a (305) Trans Am. I am curious how hard the conversion from my Tbi unit in my 87' K5 would be? Has anyone done this or know of any material online to help me out. Is it as simple as swaping fuel pumps, harness, sensors, and intakes??? Any help you can give is greatly apprieciated.
