plastic brake pedal switch with vacume line

anybody know what this switch activates? its from an 89 with the bendix anti lock brake system. i have swapped it all out for the 95 booster/master and all. the 95 pedal assembly uses a differant brake light switch, which i have used by splicing in the pink and light blue wires. the brakes work great, the lights work perfect, no problems. but i didnt reinstall the second switch that was on the 89 pedal assembly. its a white plastic pin style switch that has both a wire connector and a vacume type hose to it. can i just remove it entirely?

i thought the switch with a vacuum line was for cruise control.

the electrical portion is for the brake lights and torque converter lockup and the vacuum portion is to disconnect the cruise when you hit the brakes...
