Just rewired my trailer to Tesla plug. Didn't work. After hours of testing, it appears there is no power to the light socket by the hitch. Am I missing some setting to turn it on? I turned on trailer mode, but that didn't help.
When I had the issues I took it to Tesla and they stated the wires was routed wrong by the factory. So that could be it if not you might have to just hardwire it to battery.
