We're planning on installing several 12V cigarette plugs throughout the living area of the coach. We're planning to run 10 gauge marine wire. We used it to wire the macerator and it worked great - heavy, flexible, tinned, etc. We want to have a separate fuse for the 12V plugs and were about to add another fuse panel. However we happened to check the Operating Manual to see if we could share this circuit with another one. We found that circuit/fuse #6 is designated solely for a recirculating toilet. We don't have one. So, we have an unused circuit on our panel, #6, that we can use for the 12V cigarette sockets. There is a wire coming off the #6 lug apparently running over to the bath but we can't find the other end of it (The color matches what's shown in the wiring schematic for a recirculating toilet in the repair manual). We'll just take it off when we wire on the new wire for the 12V sockets.

FWIW
