Anyone know what color, guage and approximate location on the firewall the factory choke wire would've been for the electric choke? How did it hook up originally? Was it a stand alone wire or piggy back off something else that was fused? Should it be fused? I assume it should not be resisted as a choke needs at least 12 volts to operate correct? It should be hot all the time right? Car originally was an "H code" ss350 2 barrel and now is a clone "W code" ss454 with a 800 CFM Edelbrock carb w/electric choke. I've hooked up everything else up as close to factory but I'm not sure though if the original motor was a divorced style choke or an electric one. I assume electric as I think mainly Holleys were divorced style but I am no expert? The car is mint but I just cant seem to locate the choke wire as I think the previos owner may have cut it out as he had a 502 and T56 trans in it.:clonk:

72's did not use a electric choke.

Correct

It should be hot all the time right?

No. Only when key is on.

I also have a '72. I'm running a 750 Edelbrock on my 396. On my Chevelle, I used the car's TCS Solenoid connector (has two wires going into it, a dark blue and a tan) for my electric choke. I plugged the choke hot lead into the tan side of the TCS Solenoid using a spade connector. The tan wire is "hot" when the ignition switch is turned on and it gets full battery voltage...perfect for the choke. This setup works fine on my '72.

Happy New Year!

Route the power through an oil pressure switch so the choke does not continue to heat if the engine stalls.

Thanks, I think I'll run it through the oil pressure switch.:beers:
