I am having a problem tracking down a problem with my break lights on my 1972 Thunderbird.

When I step on the beaks the lights don't work and if I stand on them they come on but go off almost right away.

Also the backup lights work off and on. If I place the car in reverse and giggle the gear selector they come on but if I touch it at all they go off again.

ALSO, the dash lights flicker on and off.

This has to be an electrical problem but I can not seem to track it down.

I am considering replacing the headlight switch but that may only fix the dash flicker.

Please help.
