Hello gentlemen,
I have a boat that has a CA50-200-12M (i think) connected via a 5-pin cable to an old FCV-522 and I'd like to replace this sounder with a more modern unit. Options are FCV-588, GP1971F or one of the TZTouch2/TZTouch3 units. My question is: Can I splice the 10-pin pigtail (AIR 033-333) to the CA50-200-12M's cable or do I need to add an MB1100 matching box to connect to those units?
I'm sure the question has been asked before but i couldn't find any definite answers using the search function.
