    Question CX21 bow panel switches

    Anyone know what the ACC switch on the bow panel controls? I’m hooking up my AT1 and wanted switched power for the yellow wire. I have checked for another harness or terminating plug that operated with the switch but nothing. I’m stumped.

    I think it depends on what options your boat came with. Mine doesn't control anything...just an extra. Perhaps the guys with rod locker fans or something?

    Thanks Dan, that is the same conclusion I have come to after checking out the fuse boxes under the console. I didn't realize that these boats had so many option choices. The fuses are installed in all the option positions so therefore the ACC switches light up like they are actually controlling something.
