where might I find the brake light switch?
The brake light switch screws into the front of the pedal box aluminum casting, located between the brake power booster/master and clutch master cylinder. Open the front trunk and pull back the carpeting around the brake reservoir filler cap (it is held down with velcro). The switch is made from white plastic with two wires going to it. The switch has a plastic lock-nut on the outside of the pedal box to hold the switch adjustment. But be warned, there is also another plastic nut on the other side of the switch inside the pedal box that sets the brake pedal height, and it is very difficult to access.

The TR brake light switch location per Brian's description and some electrical information: Image Unavailable, Please Login If the blue/black wires are +12V with the key "on", but the red wire does not go +12V with the brake pedal depressed = buy a new switch If the blue/black wires are +12V with the key "on", and the red wire does go +12V with the brake pedal depressed, but the brake lights still don't work = most likely a bad connection at the fuse-relay panel where this red wire signal (needlessly ) passes into the w connector and out the y connector: Image Unavailable, Please Login (IMO, a good reliability upgrade is to add a jumper wire to directly connect the red wire in the w connector to the red wire in the y connector so the surprisingly high brake light current of 8~10A doesn't only pass thru two of those flaky female-male terminals of the fuse-relay panel.)
