Choke Wire....

I have a 88 ford bronco with a 351 W motor in it and When I got it someone put a Elderbrock Carb. on and never hooked the choke wire up that opens the choke. Could somebody please tell me where this wire gets hooked up at. There is no wire anywhere to be found that goes to the choke unit. Someone told me not to hook it to a 12 volt source or I will burn it up. Please help me with this as I am going nuts trying to find this out.

Thank You

On the 85 Bronco that I had it was connected to a post on the back of the alternator. Not sure which one, and I don't have the vehicle anymore, but I know it wasn't the main battery connection that has the boot on it.
