1996. I had a new trailer plug wired in ( old one was worn ) and now I don't have a 12 volt supply. Problem is, I don't remember if it came with one.
Anybody know?
If you mean 12V for charge line, the coaches were not originally factory-wired with one, even on the 6-pin.
Many have added that line when setting up to tow.
Some extra info: 12 volts at trailer plug (https://www.foreforums.com/index.php?topic=48681)
