My camper is already converted from a PV a Kombi step without power is already fitted and I also want to fit a rear interior light powered from the vehicle. Reading the forums, it appears that I should be able to find wiring above the slider and at the top (some say bottom) of the B pillar. What I ideally want is a switched supply which I think the rear light in the load compartment may have been or is is a simple pos/neg? My T5 load light was switched, but I can't remember where the wiring went.
To save me doing unnecessary investigation and pulling panels and carpeting about, could someone please point me to exactly where I can pick up a switched feed
