yeah, the parking switch contacts. that does sound like a neat
alternative switch you had. i have a micro switch on stock dash
switch for washer function, little L-bracket, radio shack switch,
grind old valve rivets off dash switch, use #6 screws to hold micro
switch, uses stock button plunger to activate.
