Default 1997 6.5 Suburban with no brake lights

Hi, all. The brake lights on my '97 stopped working, but all the other lights work. Before I condemn the switch at the brake pedal, I'd like to check for power out of it at the relay terminals. There's no brake relay in the fuse/relay box under the hood (driver's side), and no female terminals in it to receive a relay anyway, even though the cover diagram says it should be there. Does anyone know where the brake light relay is located? Thanks in advance.

I should have said that the previous owner wired in a TAP Brake Master for towing. I don't know anything about that system.

It's the switch. I jumpered the orange and white at the switch connector and got brake lights back. I have a vague recollection from years ago, when I replaced the switch before, of losing a really thin metal bushing that slips over the post where the switch sits before you put the switch on. Does anyone know anything about a bushing?
