So I thought it might be interesting to see my dash upgrade and complete rewire of my recently purchased 23 Cougar MTR. I have scrapped nearly all of the wiring, switches and gauges and am in the process of upgrading to NMEA 2000 bus everything. I have decided to go with Livorsi Vantage View gauges with a Mercury NMEA gateway. Also adding a Lowrance HDS 7 touch and Livorsi LED indicator for the trims and jacks. I have learned a lot about NMEA 2000 in a short period of time but I'm sure there is plenty more to go so feel free to ask questions and make suggestions. This is the dash as I got it. This is my Photoshop mock-up to sort the layout.
