1974 318 choke question

I recently installed a 1974 318 from a scamp into my 65 coronet. It was a drop in instillation and went wonderful, motor runs great.
Here's my question, the 74 motor has what looks to be an electric choke, at least there's a rod that drops into the intake right next to the carb, it has a small electric attachment box next to it. this little box has a battery wiring attachment to it. I attached a hot lead right to this and nothing happens so I'm assuming there's something wrong with the choke.
It's a two barrel carb, and I want to keep it that way. Once it's warm it runs great but it wont come off the fast idle cam even when it's hot. I've turned the fast idle screw out so that when it starts it runs at the normal rpm but never fast idles when cold.
Can you let me know what I should do? a picture would be great too. Not sure if I should leave that hot lead on there or if it should go through the switch.
Thanks, Dan.
