The two pin inline brake switch is the way Ford used to do their brake line switch. It is hydraulic in that the brake fluid pressure activates the contact and connects the switch. Most modern cars use an mechanically operated electric brake light switch. You push the peddle down and the switch is activated. Look around the brake peddle under the dash in a modern car, you will see it. I would be interested in seeing what you have done. Thanks, Jim
