This is how I went about mine and how my switch hooked up.
The front pair is for the brake light switch. When the plunger is opened (pedal depressed) the switch is closed and brake lights light up.
The rear pair terminals are for the TCC and Cruise Control. They are normally closed. When the pedal is depressed these circuits open cutting the power to the TCC and Cruise control.
I relocated my switch so it couldn't be seen below the dash. See Post 177 here:

Hussy's right, on the 4 pin brake switch 1 pair is normally open(cold, the brake light switch) and the other pair is closed(hot, runs the cruise control or the TCC switch.
