Getting ready to swap carbs from manual choke to auto choke. How do I wire the choke so that it works properly? TIA Pete and Nicholas

What kind of carb? Most electric chokes need 12 volts only with the key on. Most chokes will need further adjustment (choke pull off and opening rate) to work properly depending on your combo.

Greg it's an edelbrock 600CFM if I remeber correctly. It currently has a 750 edelbrock on it with a mild cam and stock heads and pistons and I feel it's over carbed for the combo. Pete

Doesn't the 70 have an Idle Stop Solenoid wire on the original harness? Can't recall at the moment. If so, use that wire.
