I looked in the service manual, and nothing on gauges. I have the rigging manual, and nothing on the gauge I have. My gauge has a removeable connector at the gauge, and it’s a 12 pin style connector with 8 wires in it.
The harness going from the gauge to the engine is plug n play. There’s another harness that goes to the side mount control. I thought it was connected correctly, but there’s no trim indicating on the gauge. Also, the engine hours are not showing up. It just says 0.00
