Are both the cabin 12V electrical system and the trailer running lights grounded to the metal trailer body?
Thank you-

Negative, or ground, is the same side of the electrical system as long as all the devices are designed to be used in a negative ground system. BUT, IMO, a properly wired trailer, cabin, vehicle, etc. will use a dedicated negative wire from each light or device, that has the other end grouped at a common negative/ground point. That point may also be connected to the frame as a ground. It is poor practice to depend on the frame as a ground conductor though.
