Wiring the ignition switch on a 1962 Ford Falcon is the same as its sister car, the 1962 Mercury Comet. The switch has four terminals labeled “A”, “B”, “S”, and “I”. Terminal “A” receives power from the voltage regulator and provides continuous (unswitched) power to the fuse block for constantly powered items like clocks. Terminal “B” provides switched power to the fuse block for other accessories and lights. Terminal “S” provides power to the starter relay and terminal “I” provides power to the ignition system.
This process does not require tools.
Wire an Ignition Switch – Locate terminal “A” on the ignition switch. This terminal should connect to a black-green wire to the voltage regulator and a black-green wire to the fuse block (for continuous power).
