I just received my new Garmin 54cv Chartplotter. The instructions do not address the wiring harness! My question is about the blue and tan wires in the harness. It is obvious the red and black are positive and ground, but the on-line install instructions say the blue and tan wires are for adding a NEMS 0183 device. I don't know what that is, so I guess I don't have one! So do I just leave the blue and tan wires hanging?? Thanks...
