When I did my engine swap, I had to use the Chevy brake light switch because it's configured the same way, but not for cruise control.
It is used to unlock the torque converter in case of a panic stop where the rear wheels might lock up and kill the engine.
It looks like I need to get the Mazda (cruise control equipped) brake light switch, so I can get rid of the Chevy one.
