Good To Know
Q: What are the four positions on this ignition switch? A: The four positions are Off, Accessory (Acc), Ignition (IGN), and Start, which allow you to control power to accessories, the ignition system, and the starter motor.
Q: Can this switch replace the original ignition in my vehicle? A: It can serve as a replacement for many 12V ignition switches, but you may need to adapt wiring or add a new key if the original key is incompatible with the new cylinder.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
