Anyway, the 61128377436 lead was only used from 09/1997 to 08/2000.

For the Mk3 from 09/2001 the loom is 61126915132

Item #5 in this picture:


But I am not sure that is the loom you want, because 61126915132 is a connecting loom for the nav into the main looom of the car. I cannot tell if it has the video module connections on it.

At any rat, you need the X5 equivalent, not the E39 loom.
