Westfalia tow bar wiring

Would the tow bar socket on a German import westfalia be wired the same as a uk trailer plug?
I connected my trailer up today and the lights are not functioning properly
I tested the trailer on my daily drive and all the lights work fine
So obviously the problem lies with the van.

I’ve had a look today and found a pile of bullet connectors behind the lhs rear light housing.
I doubt that’s how it was originally done but it’s what I’ve got to work with now.
I’ve pulled apart each connector and cleaned it up of corrosion
The trailer still isn’t playing ball
The indicators on the van are flashing the tail lights so I think it’s been wired up incorrectly
Can anyone tell me what wire colours on the vehicle loom to match to the tow bar wiring colours please

With the left hand indicator on I’m getting a voltage on the black wire with a white line in the vehicle loom
That’s connected to the yellow wire on the tow bar loom
So that seems correct
Yet when testing voltages on the tow bar plug there’s no voltage on pin one which should be left hand indicator
It’s appearing in pin 2 instead
The strange thing is I’m getting continuity between body earth and all tow bar pins

All sorted the socket itself had been wired up completely wrong.
