Just one question about the ignition switch because I just read this post, but which terminal is the accessory terminal on the switch? I know there is one for things like the gas gauge and lights, and another that goes to the power source, but is that other terminal used for things like the heater? Because currently I have nothing attached to one terminal and my wiring diagram instructions had nothing in them about that terminal. I have an aftermarket turn signal kit and the heater that I will have to attach to the ignition switch.
