Your Lokar shifter may already have a micro-switch installed that has both N.O. or N.C. terminals on it. Depending on how Lokar trips the switch, you could change the connection to suit.

(Preference would be to use the NSSopenPN circuit. It will only be energized when the car is running, and is a somewhat "Fail Safe" design... if the relays fail you can start or unlock the car.)
