Open-to-Stop Wiring Connections

For an open-to-stop kill switch, the circuit to the engine or engines from the kill switch is normally closed, and when the circuit opens, it causes the engine to stop. This type of kill switch is used more rarely and is typically found on vessels with inboard engines.

Orange and pink open-to-stop wires from the GOS™ 10 hub wiring harness

In an open-to-stop installation, you must connect the orange wire from the wiring harness to the positive wire from the existing kill switch, and the pink wire from the wiring harness to the other end of the signal wire going to the engine. By routing the kill switch signal wire through the GOS 10 hub in this manner, it allows the system to open the circuit and kill the engine. This preserves the functionality of the existing kill switch.

If your vessel does not have an existing kill switch, you can connect these wires to the ignition signal wire instead (Connections for Vessels Without an Existing Kill Switch).

Ground wire from the GOS 10 hub wiring harness

You must connect the ground wire from the GOS 10 hub to the same ground location as the engine for the engine cutoff system to function properly.
