Remember that this [HDS or CHIRP] is an advanced unit with built-in interface, NMEA 0183 in/out, NMEA 2000 for networking and Multi-Window display. Some of those wires may be for add-ons you may already have or do not yet have. Let the manual be your guide. If you install the unit and it working properly, just put the remaining wires in storage. One of these days, they will come in handy.
