Installation Notes

Before installation, disconnect the battery to prevent shorts. Label each wire before removal – even if the old switch is dead, wire position tells you where things go. The 5 pins typically handle battery input, ignition, starter, accessories, and ground. Test all positions after installation – OFF should kill everything, RUN should power gauges and engine, START should engage the starter. Many operators keep a spare switch in the toolbox – when these fail, it’s always during critical field operations.
