This safety switch kit has one roller switch that allows you to start the vehicle in park or neutral. The second roller switch operates in reverse to turn on your reverse lights. The kit includes the two switches, mounting brackets for the two switches, the two cam plates, and hardware.

It's extremely easy to wire. Instead of running the ignition wire from the starter switch directly to the starter solenoid, you'll now run the wire from the starter switch to the park switch and from the park switch to the solenoid.
