New to site. Have a 65 F100 240 I6. Have begun to install an ez wiring harness, and want to have two toggles and a push button ignition. The wiring harness wire are labeled, ign sw pwr, ign sw ign, ign sw acc, ign sw acc, ign sw start, and n. safety sw.

I need help decideing which wires go which switches. Any help would be greatly appreciated. Thanks

 

The push start button should be hooked to the ign sw start. Maybe.


I'm done. I give up.

 

The original switch had three wires and a post. One wire is battery hot comes from the fuse box. One wire is ignition hot (key on provides 12v to the coil). One wire is start relay through he neutral start switch. The post provides power for switched accessories like wipers and turn signals.
Toggle 1 12v from the fuse box to the start button through the neutral start switch to the S post on the starter relay and from the toggle to the distributor.
Toggle 2 12v from the fuse box to the accessories side of the fuse block
Turn on toggle one power is provided to the distributor and the start button. Push the start button power flows through the neutral start switch (provided its in neutral or park) to the starter relay energizing it and providing power to the starter.
Turn on toggle two power is provided for the accessories ts, heater, radio etc.
Some components operate on constant hot circuits, stop lights and 4 way flasher for example. The light switch also uses battery voltage from the fuse box.
I sure would not wire a truck in this manner unless I was racing it. New stock switches, bezels and lock cylinders are available

 

There are TWO possible ignition switches.

The original 1961/66 switch: C3AZ-11572-A (replaced COAB-11572-A) was replaced by Ford in 1967 with another switch (C7UZ-11572-A) for use as a service part replacement. Has an extra terminal.

The C7UZ switch was factory installed in 1967 Econolines & 1967/77 Bronco's. FTE member Confederate Diesel has the wiring schematic for the C7UZ switch.

The push button starter switch used on 1952 trucks (2C-11500-A) is available from Ford. This switch was also used as the windshield washer switch on 1965 F100/250's, 1966 F100/250's w/single speed wipers.
