Quick question, i have a 07 yamaha 90 two stroke and have a harness not plugged in. It has a green, green/red stripe, grey, and pink wire into a 4 pin harness. Is this normal not to be hooked up to anything. Also, is there anyway to test to make sure my buzzer/alarm is in working condition.

If its an off white colored square connector then that goes to the yamaha gauges with warning indicators, engine warning system will still work with or without gauges installed.

If have the Yamaha switch panel with key switch and landyard on panel then the landyard disconnect alarm will activate when turn key to start position, when engine cranks over the alarm should come on. If switch panel does not have landyard included may not get the alarm.
On the two stroke models can ground the pink wire of temp sensor on cylinder head and turn key to on position to activate alarm.
