Eb,

I agree with what Tiny has said, but interpret your question a little differently. If the two speed switch is part of the fan/motor, then you would merely take the wire that plugs into the cigarette lighter and wire it into a switched connection somewhere.

Does a '63 have a fuse box? Are there one or two spare tabs that switched ON with the key. Couldn't you stick your fan on one of these.

I would guess you want this thing off when you turn the key OFF. However you decide to do it, make sure you have a proper fuse in the circuit.
