Ignition switch

This is a side-by-side comparison of the three different ignition switch styles used in Ford pickups during the '67-'72 era. On the left is the '67-only switch, which utilized a single hot stud which protruded through the push-on connector, which in turn was held on with a small nut. In the middle is an example of a '68-'70 ignition switch, in which the harness connector was pushed onto bullet-style connections. The '71-'72 version on the right, introduced in mid-'70, utilized a similar style but used spade-type connectors.
My new project came Tuesday, and well it is a project. It had 2 ignition switches, one in the dash that had a key jammed into it, and one hanging down that started it with a screwdriver. It is a 69 GH truck.

I am trying to track down what wires for the ignition switch went, and did a search and came up with this. Looks like I have a 67 style (far left). In the picture above, and that switch must have had some problems also, as I had 3 hot terminals with the switch off.

The middle was a hot, Powered.
Then the ignition wire that caused it to crank, was in the right place.
The other wires (group of 3 connected together) were hot all the time, that I assume should have only been hot when the switch was on,
There also was another hot wire running to the remaining terminal inside the plastic ridge.
The one on the outside of the plastic ridge do nothing, even when I put a hot wire to them.

I now added a universal switch to it to get it around, and it starts and runs, and everything is operating, BUT I have 2 wires that were outside the ridge, that I don’t know what to do with, and wondered why I have a hot wire that ran to the switch, that makes no sense on what it should do.

Thanks

It should have at least one wire that is Hot all the time from the battery (could be a group of wires)... If you can let me know the color codes of all the wires I might be able to tell which wires are for what... The center one is the power to the fuse box, it should only be hot when the key is on or acc.

Here is one that I did but it only has 3 connecters inside the ridge instead of 4... the one that is labled ??????? I believe is for the brake warning light and it should ground when the switch is turned to "Start" to turn the light on.

If it Looks good and Works good then it's ok by me. Everything has its issues from time to time...
