Correct me if I'm wrong, but if you are only trying to insure that you don't
accidently energize the lock out, then all that is needed is to instal a warning
buzzer on the lock out. That way, if you accidently energize the lock out while
driving down the highway, the warning buzzer will sound until there is actually
pressure put on the brake pedal to silence it. I can assure you that if I were
to accidently bump my switch into the "ON" position, I would immediately know
about it. Mine is a "Mico Lock" unit and it comes with this option installed.
Just my two cents worth.
