I’ll finish the rewiring of my trailer and then connect it to the car and see what happens. Presumably the red power feed is a constant 12 volts so that the trailer lights work even with the ignition off?
Yes constant feed to the trailer module
No , the trailer module supplies an output to the relevant trailer lights when it gets told to by the car's computer network system . The trailer module listens for commands from the car to switch the trailer lights on or off . It will probably not work if the Caravan has LED lamps ... This was allowed for from about 2012 ..
