I'm trying to install the bmw ugdo in my 2003 e46 touring.
I bought it on ebay a week ago.
but it seems my e46 is not prewired : I can't find the 3 wires cable
under the roof...
does anybody know the wiring for the 3 pins of this ugdo ?
and where can I get the correct wires somewhere not too far to make the
cable myself ?
with best regards,
