I haven’t yet been able to extract the grey plug with the heavy red power cable feeding the trailer module so I can’t be sure that the module is getting power. I was getting voltage at the socket on the tail light pins but when I think of it, not the full 12+V. So perhaps there’s no power in?
I’m not sure what you mean by “plug A going to the socket”. Is that the 12 way connector that connects the tow bar socket wiring to the module?
