@lout Clear as mud xD looks like I might just have to bypass the controll module and use a standard wiper motor.
@Fu Manchu you should be able to slap a button in the x8 and have it pop the glass, id imagine it runs off the same signal at the bcm, on my wagon it didn't have the wire so after adding a pin at the bcm and button in the glovebox it all works as it should.
Thanks for all the pics and doccos guys, I'll have a dig through them and see how far I get, might document it all if I get it working right.
As it stands the only thing that doesn't work is the wiper, that's fine for me because the boots just about packed to the roof every day.
