Wiring should be very straightforward, the connector on the left (looking at the back of the sounder) is the plug for the transducer, the 2 pin plug in the middle is for the power (notch in the plug cord points UP), and the 4 pin connector is for the optional speed and/or temperature sensor. Here is an install manual for your reference:
