Checked fuses, all ok

In the process of adding grounds, engine to frame, cab to frame, box to frame.

I’ve traced the brown tail light wire and so far no kinks.

Any suggestions


Might help if you told us what it was.

My 51 Plymouth uses a hydraulic pressure switch tied into the rear brake line to actuate the brake lights. That's factory, BTW. If it leaks internally it will do what you see.
