automatic choke

I've replaced carb. on a 1981 Silverado 305 with a Edelbrock carb with electric choke. I do not know which wires were connected to the original electric choke. By using a test light to complete a ground I've discovered two different "hot" wires that cause the 'choke' light to come on when the grounded via the test light (my 12 volt test light lit up as well as choke light when touching wire while aligator clip is grounded). What wire should I use to connect the choke? Is there some type of test to determine the correct wiring for an electric choke?

Any wire that is 'hot' when the ignition switch is on and 'off' when the switch is off will work. Connect it to the (+) terminal on the choke housing. The other (-) terminal on the choke housing goes to ground.

Ditto with Frisco, he gave all the correct info, if you follow his recommendations you wont have a problem. Adjust the choke when motor is completely cold and have a 1/8" gap when closed, when it cold it may have to be adjusted again.
Luv the smell of NITRO in the morning.
