That setup is for replacement on an application that already has a hot air tube protruding into the exhaust crossover (on a V8, obviously).
The easiest thing to do would be to replace the black plastic choke thermostat with one that has an electric heater in it. Holley sells them, they're on eBay, etc.

JC Whitney and similar vendors used to sell hot air choke conversion kits that bolted to a header tube, gathered hot air, and sent it up a piece of tubing that screwed into the hot air fitting on the choke housing. I haven't seen one of these in years, but it might be another option for you. If you're handy, you could probably fabricate something similar that would work.
