Late ignition switch
 

Looking for diagram for late ignition switch I’m working on55 F100good need help

Can we ask why you are looking for this?

If I remember correctly,,,,,,,,,,,,,,,,,,,,the switch is mounted on the lower left side of the dash to the left of the steering column.
It has a multiple wire plug that gets pressed on to the switch assy. There is usually a battery feed , a wire to the ign coil, and a wire to the starter solenoid (through neutral safety sw or clutch safety sw) .There may also be a wire to supply accessories.
Have you removed the old sw yet?
