I want to fit a double USB plug in the cab area of my motorhome, so it is permanently live. I am conscious that there have been a number of threads that talk about the management systems on these vehicles being upset by various additions. Not understanding most of the technical detail, I am hoping for some help in telling me how to wire the double plug into the system without causing any problems for my self.
Thanking you in anticipation
