Welcome to the group
There is a fuse panel on the driver side, under the dash. On my Bounder it just looks like a section of dash. But you could pull it off and there was a fuse panel, turn signals, dash stuff fuses. I am not sure how this cig. lighter would have power when you are hooked to shore power, I ain't that smart, and not have power when the generator or engine is running.
Good Luck Keep us posted. Peace D
