Getting a code are ya?
The TCC brake switch operates opposite of the regular brake switch in that it supplies +12 all of the time unless the brake pedal is pressed. You can simply test the appropriate wire at the PCM for proper operation of the switch to begin. Depending on your findings, it couls be a fuse, switch, wire or PCM problem.

The switch itself is located up under the hush pannel. So drop the drivers side hush pannel and look at the brake pedal assembly. It is sorta creme in color....depress the brake pedal and you will see how it works.

Well, the PCM is above the passenger'* hush panel and the TCC brake switch (along with the regular brake switch) is above the brake pedal. My 93 manual is showing Fuse 16 is the power source, the wire is purple in color and the PCM cavity is Connector 2 cavity A5
