YANMAR 2GM20 electrical harness question

The two engines on my FPTobago 1996 connect to the controls with extension harnesses. In each case, there is a litt e rubber box, 5 cm X 4 cm X 3 cm, with 5 or 6 wires coming out of it and joining the other harness wires on the way to the controls. The box is cable-tied to a flange om the saildrive at the back of the engine, port side.

No info on the box in the wiring schematics.

I am troubleshooting a false alarm in the circuit from the saildrive diaphragm water sensor.

What do the boxes do?
