Connecting up a remote locking system

[Hank]

I purchased a 1995 318ti from Germany in March 2022. It has a total of 63,000KM / 39,000MI. I would like to add a remote door lock system. I have purchased a British Hawk 008 unit that is compatible with my vehicle.
I found out that the wiring, as well as other items, on the "made for Germany" cars is different.

Does anyone know of a source of manuals that would have the European wiring diagrams for this vehicle. I have researched to the best of my ability and am coming up short.

Thanks folks, Hank----I am an old newby
