We removed the large electrical box that the military used with their towed generator. Also removed the blackout light control box and the overhead fluorescent lights. Had to reconfigure some wires in the raceway but did not use a schematic.
Are you referring to the solar setup? I found a proposed diagram from 01/2018 but we elected to overbuild the wiring to make the system more efficient. Most tech support was by phone. Bay Marine Supply was excellent! Also had great prices, highly recommended.
