On our 8V71 's at work it is connected to a circuit that allows the engine to stay running. No fuel pressure; shuts off. However those engines have a Woodward hydraulic governor. Yours does not. May also be used as a "run" circuit to send power to various things to signal the engine is running. It has been a while since I've had to mess with that engine. Pretty reliable.
