I have a newer C26 2016 and use the wiring diagram from 2013 manual. I don't think there is anything different about the wiring diagram with the inverter then without the inverter. Except missing , the inverter, inverter battery switch, 175 amp fuse, #1 red to the battery terminal + House, #1 yellow battery terminal to house battery terminal - , #2 yellow Frame of inverter to aft grounding bus, and 10 gauge boat cable coming off the inverter 120V side to the fuse panel selector switch. Block the items listed out and the wiring should be the same. I purchased my C 26 without the inverter because I wanted a 2000W Pure sine wave inverter. The inverter that was offered then was a 1500W modified sine wave inverter. I didn't see anything different about the wiring in my 2016 boat without the inverter then the manuals diagram illustrates.
