i am stuffing an 85 305 tpi motor in the 88 lO3 tbi firebird and staying with the tbi setup. I got some work done to the motor and got a holley throttle body and mor goodies. I don't want to go with the surpintine setup because it will burn a bigger hole in my pocket in the long run. 85tpi had two wires on top and one wire on the back from the battery. the tbi setup has the three wire connector and the battery on the back. How can I Wire this up to work?
