66 ignition switch original harness plug wiring help

Need some help please. The original owner cut the original plug for the ignition switch and I’m looking for the wire configuration of the original plug as I have a replacement switch that takes the original plug and there is no markings on the new switch as to what the lugs are.
I’m betting someone here has the wiring configuration of the original plug so I can determine what wires to plug where on the new ignition switch.
Ultimately I would like to find an original plug and put it back.

Thanks in advance with any help.

I'm assuming the ground is the center post as it looks like the trace goes into the switch, but I'm almost betting the 4 lug on the switch is ground as well. Just not sure.
Hopefully, there is a diagram out there that will show the socket wiring.

...once you wire the new pigtail to your wiring harness, I believe there is only one way the plug can connect to the ignition switch.

Agee, but I need to know how to wire the new pigtail socket. I'm going to purchase the new pigtail socket from LCM and hopefully the wire colors will help or keep searching for a diagram that will show that socket.

thanks Dave. I just found this exact one and pretty sure that top diagram will do it.

There are TWO possible ignition switches, which one did you get?

In 1967, Ford replaced the original 1961/66 switch (C3AZ-11572-A [replaced C0AZ-11572-A] Motorcraft SW-353) with the '67 Bronco/Econoline switch (C7UZ-11572-A/Motorcraft SW-583) that has an extra terminal.

The original switch was also used on 1960/64 Galaxie; 1961/64 Thunderbird; 1965/66 Mustang.

Note: Dave's 1st diagram in post # 8 titled EARLY IGNITION SWITCH is actually the LATE 4 terminal switch, because the brake warn(ing) lamp was introduced in 1967.

I got the late switch with the 4th terminal that I figured wouldn’t be used.
Appreciate all the help and hopefully the socket pigtail I ordered will fit. At least the diagram shows the wiring of the switch. Can make it work now.

Really appreciate all the help & wanted to post an update and ask one more question.

New switch, bezel, & socket plug wired and installed & working really well.

Is there a large grommet or something similar that is supposed to be put on the ignition switch that helps push it away from the inside of the dash? I modified a piece of pvc to hold the switch back to apply pressure so the bezel & switch stays in place.

C1TF-10A885-A .. Instrument Cluster Control Mounting Plate (this is the spacer between the switch and the backside of dash) / Obsolete
