I noted that the key switch has three connections: "Pwr", "Ignition On", and "Start". "Ignition On" is connected to "Pwr" when the key is turned to the right, which provides power to the panel and engine electronics (via a ckt breaker).  "Start" is connected to "Pwr" when the key is held to the far right against the detent and is connected to the Starter button which will activate the starter solenoid.

I am thinking that the relay should be connected to the Start position which will energize the glow plugs only while the switch is held to the right prior to starting. Can anybody confirm?
