Hayden Fan Controller Wiring Question for 67 Dart 318

THE FIRST THING WE NEED is a link to the Hayden destructions so we can see how it's wired. If you tie it to the "ignition run" wire you need to be BEFORE (on the "key side") of the ballast resistor AND AND AND!!!!! AND!!!!!!!!!!!!!!!!!!!!!!!!! you need to be ONLY triggering a CONTROL (low current/ trigger) circuit and not the main feed.

How large are the thermostat sensor wires?
