I also have a lot of extra wires under my console with nothing plugged in to them any idea what those are for, including what looks like i couple of them with harness plug ins
Most of us have unused wires under the helm, their use depends on your options .Fewer wiring harnesses across model lines is cost savings for any manufacturer
if you email bennington directly they will provide you one for your specific boat
