Someone please correct me if I give wrong advise here as I am going from memory. On the choke housing, you will see +/- listed next to each of the terminals. You will want to run a very short wire (4-6 inches) from the negative terminal to a ground. Most I have seen are grounded or attached under one of the screws on the carb body. The positive wire is much longer and I have seen recommendations that you connect this wire to the wire that powers the windshield wiper motor for a couple of reasons. This power source supplies the right amount of volts to make the choke work properly, and it turns on and off with the ignition key. Once connected, you will know it's working in a matter of 1-2 minutes as the housing will get very hot to the touch! And obviously, you will see the choke butterfly start to open.
