What about power at the bulb socket when the pedal is pushed? Maybe a wire between the brake switch on the pedal and the socket is bad?

Do you have a meter? Check continuity between brake light switch wire and wires going to socket?
Just a thought... is the plunger switch working/adjusted right? Like it didn't come away from the pedal?

seperate the dangling electrical connector for the br/ts under the steering column & with your VOM on the column half see if you have continuity between the white "in" wire from the brake pedal switch and the 2 "out" wires to the dr/pass respective brake lights with the stalk in neutral. Not sure of the colors but if in doubt www.mymopar.com will have them for you. Your turn signals work so from the electrical connector behind the DR kick panel rearward you are good

TS switches are notorious for failing. Other places have 'em, also. https://www.yearone.com/Product/1966-74-a-b-e-body/fd93103Quote:

If memory serves, brown is right rear lead, darkgreen is left rear lead, they're adjacent to white lead in the TS harness plug.

Don't know for sure about '70, but if the column is similar to '72, it might be possible to change switch with column still in the car. Steering wheel needs to come off. Then you SHOULD be able to feed the bottom of end of the TS switch harness plug and wire bundle back up through the wire tunnel that is provided along the underside of the column. Some have attached a flexible wire or string to the bottom harness plug, so that you have a way of pulling the new harness plug back down through the tunnel. Check this thread for some pics... https://board.moparts.org/ubbthreads/show...rue#Post7172387
