The transducer is a simple plug in on that, try it out and spin the paddle.
Then again, you didn't picture a transducer so I deduce you don't have one and maybe the previous owner had not gotten around to the through hull either. That means you are lucky and get to pick which part of the boat gets wet on a regular basis.
That being the case any NMEA 0183 compatible unit will work and can be wired in. It's only 3 wires, the wiring in the manual conveniently leaves out which is which (got bored at lunch time and read it).
In order to get all your displays working and talking and in particular to get the true and apparent wind to calculate properly you will need the speed log running in conjunction (talking to) your windex.
