I'm about to pick up an ISUZU NPR 250 that is 24v and has a separate 12v system for the trailer. It's been properly set up by a motor vehicle electrician.
I'm going to add a 12 pin plug and video screen so that I can tow my 5th wheeler.
Can I earth the 12v appliances (video camera and earth on pin 10) back to the chassis? Or do I need to run the earths back to the 12v system?
