Best place to pick up 12v switched power for choke?

[Scott76]

I bought my truck down south and it had a Holley carb with no choke provisions. I've since bought a Quick Fuel carb with an electric choke. I'm not great with electrical and was wondering if there is some conventional wisdom on the best place to grab switched power from?

I know I've been asking a lot of silly questions lately but I'm coming from motorcycles for the past 20 years so a lot of this is completely new to me.
