Hello! New Range Rover L322 Owner Tow bar electrics querey

I have just purchased my first Range Rover, a 2003 L322 4.4V8 petrol Vogue. Loving it! I'm used to fragile cars (serial classic car restorer; particularly complicated hydraulic Citroens) so appreciating the build quality but also well used to questionable electrics and suspect auto gearboxes. I've always admired the design of the L322 and when i needed a new tow car felt it was time to take the plunge.

I have a question about the factory spec Westfalia tow-bar electrics fitted to my car. My car seems to have all the right ECU boxes in the side cubby but only has a 7 pin socket. I want to fit a 13 pin euro socket with all the pins functioning as they should. I don't want to buy a new (or S/h) box to tow bar loom as they are stupidly expensive. I am an experienced with electrics so I am hoping someone can give me the pin out diagram/list for the ECU which would enable me to make the loom myself. The issue is not the tow bar end-that's easy-but which of the empty pins at the ecu plug do I connect the extra wires to.

Hope that makes sense.

Welcome.

Thank you; seems like a lively forum.
