check near or on brake master cylinder.  Usually there, at least in later stepdowns.  Looks like a little screw-in knob with two wire tabs

You could fit a new one on the master cylinder, or see if there is an existing switch along the pipeline. On my 36T I have a brake switch in the pipeline near the rear wheel. Finding it or installing a new one would have to be the easiest job to do when restoring a car. I wish all my problems could be so simple Barry
