[Healeys] Brake Light Switch- not behind ignition

[Bob Johnson]

I am about to install a mechanical brake light switch on my Phase 2 BJ8.
Wiring it like the original pressure switch is easy, but I would like to have
the brake lights come on when I press the pedal whether the switch is on or
not. It has been discussed before, but I am not clever enough to use the old
archives to do a useable search. I am going to mount the switch on a bracket
attached to the heater box. I believe that I can use either the brown radio or
lighter wire from the ignition switch and then run a wire (hopefully green
purple) under the hood (American) and replace the single connector going to
the rear of the car with a double connector and leave the pressure switch and
wiring in place. Will this work?
