Just pulled the tupperware off for the first time, Not that bad to do!
On the left rear side, by the sub frame rail is a electrical connector with nothing plug into it.
Does anyone know what this is ???

It's for the bmw alarm system. I used it to power my extra led brake lights.
1 wire always hot
Brown ground
1 goes off with ignition
forgot what the last one did, it's been a while
I haven't had any problems since tapping into it
