OK, so this raises a question. Can a three prong switch be used in
lieu of a two prong switch?? Thus leaving one prong without a wire to
it. Will the brake light system still work properly?

What are the differences in the wring that a three prong switch would
not work in place of a two prong switch.

Thanks.
