Ignition Switch

Question!

Can't find a key for ignition switch for my dune buggy. It's based on a
'66 type III. Finally giving up on keeping it with the stock switch.
Can't get the lock cylinder out without the key.

Bought a universal switch just so I'll have a key and a push button
starter which was plan A to begin with. I know how to wire the
pushbutton in for the starter but anybody got any suggestions for the
key switch? I'd like to have an accessory line for the radio and then a
run position. The switch I bought has provisions for that.
Specifically, which wires coming from the steering collum are what.
They are all red.

While you're at it. It was 6v but I'm changing it to 12. For whatever
reason, there is a second solenoid wired in back there, it's an old
Ford type. I remember reading somewhere, probably in John Muirs book,
about doing this but I can't remember why and can't find it in the
book. Anybody know?

Thanks,
