neutral safety switch?

hey everyone. has anyone wired a switch to a b&m ratchet shifter. it has 2 switches inside it- 1 for reverse lites, which i'm using, the other for nuetral start. switch in shifter only has 2 terminals. can't use factory switch cause strap from trans shield covers the terminals. thanks fir ur time. seeya.

Yes I have done the exact same thing. I wired the switch so it provides ground for a relay.

I have mine wired on the b&m switch.It's mandatory in IHRA drag racing.I did see a guy at are local trac without one crank his car in gear and hit the car in front of him.neither car could race the next round. hope this helps.
