I then allowed it all to dry then reassembled. Still no brake lights! I'm thinking I need to check the brake light switch under the brake pedal........what is the best way to check it out?

Un-plug the wire connector, key on check for voltage, do not re-connect the wire until after the switch is tested.

Ohm test the switch brake pedal applied and off, no change = bad switch.
