Ok, I have an HEI distributor with the 4-wire plug on it, I know it go to an ignition module,computer behind the glove box, but it had a 305, now it has a 350, it runs, but theres a vacuum switch/sensor on the firewall that I beleive is a tip-in switch, and theres a knock sensor which is connected, my question is, what was the factory appropriate supply of vacuum for it? I looked up vacuum diagrams for 305 & 350 and they either dont show it, or have many different configurations, as well as the tranny torque conv. Vac switch sensor as well,????
