Does it have a 7 pin transducer plug?
If so, I rewired my old transducer which is an Airmar 7 Pin.
But rather than cut off the transducer cable. I removed the socket for the plug from the old unit and wired it up to another head unit, an Eagle color display. But see I am an electronics minded guy. That transducer works perfect for depth. Speed it can be adjusted in the software. The temp, I used a variable resistor to modify the ohms.
I have this shared album here.
basically, I just paralleled the corresponding wires, wire for wire. So these Eagle heads have double sets of plugs. I could use either the Apelco transducer, or the Eagle transducer.
