How to replace a brake light switch on a honda prelude?

All you need 14mm wrench. When your laying on the floor board disconnect the 4 pin connector that is on the brake light switch. If you cannot get your fingers on the lock tab on the connector take the 14mm wrench and loosen the jam nut that is on the brake light switch and rotate the switch until the lock tab is exposed. If you look at the new switch you will see the plunger that will make contact with the brake pedal switch. When you install the switch make sure the switch is fully depressed but make sure that you don't cause the switch to push down on the brake pedal or it may cause the brakes to apply. All you want is the plunger to be pressed down if you screw it down to far the metal part of the switch will make contact with the brake pedal and start applying the brakes. Good luck it really not that hard.
