Recently I installed a new light and brake / stop light switchs on my 1969 Ford Mustang Mach 1 and yet, I still have no brake lights working.
Although, all other lights ( turn signal, emergency, head- light are working) and I have only one wire at the brake / stop light switch that as power.
Thus, any idea why is my brake light are not working?

I installed a new turn signal switch in the steering column, and it fixed my brake light problem. Evidentally the turn signal and brake light wires use the same plug wires. It cost about $70. I would suggest doing this.
I have a 69 mustang and I had the exact same problem. All the lights work but when I go to put th shifter in reverse, no lights. I have a three speed and coming down on from the fuse box is your wire which when you ground it, your lights turn on. I fabricated a piece which when I put it in reverse, the ground wire would touch the linage thus giving me back up lights. This worked for me..

Most tail light problems are a result of a bad ground......somewhere.
