Didn't know exactly where to put this one. Sorry mods.
So I found this most excellent site for EVERYTHING wiring on our Z4s!!!

I found this looking at how things are ran inside there before I start getting into something and messing something up...
If you've seen this site before, awesome, but if not, I REALLY hope this helps people in the future!!!
