I've received the transducer from the guy on Ebay.  The unit he sent has 4 wires and a shield.  I do not have the boat here so I can't check the existing wire/cable coming from the current transducer.  I do know the harness is 4 pin with certain colors (see below).  The unit I received has totally different colors so now I need to identify which goes to which.  I checked the resistance and the only ones that were not infinity were Shield to Green (3.8 m-ohm) and White to Brown (13.2 k-ohm).  All other were of course, infinity.  You folks have a clue which wires match up to the harness?
