Just hook it up to a switched 12v source. Don't go off the coil. You might need a special connector that goes over the metal pole on the choke. Make sure the carb is grounded.

You only want the thermostat's heating element "on" when the key is on, otherwise the choke will always be open.

Originally, the electric choke was triggered by an oil pressure sender that allowed the choke to heat up when the engine was started up. That can still be done if the sender is there still. IIRC, it was back by the distributor, and had 2 prongs on it.

Otherwise, use a wire that is only "hot" w/the key in the "run" or "run" and "start" position, dead in any other position. Usually there's a circuit in the fuse box for accessories that will work like this.
