Welcome to 2CarPros. Is this a conversion van or extended work van? The wiring diagrams I have don't show a rear outlet from the factory. I have seen them in conversion vans though.
The OEM lights are on fuse #8 which is a 15 amp fuse. If it's a conversion van they usually hide the upfitter fuse box behind a trim cover. Most are behind the drivers seat in the sidewall.
