Could the fix really have been that easy?
I pulled off the cover under the dash to inspect the TCC and brake light switch. I could not remove either of them with a 1/8 turn and folks in my office were looking at me funny laying on the floor of my car.
I notice that my TCC switch has a vac line and yours was totally electronic. I popped the hood and found the only vac line between engine and the firewall was disconnected and heavily dry rotted. I reconnected the hose and the problem seems to have resolved itself
