Johanas,read my post #3 again..the answer is there!
Your Spider tail lights are facelift and you need to swap the pins on the cars oem plug...NOT the tail lights.
You do this by releasing the white tabs in the pic and swapping the pins as per my post #3.Easy mate ....good luck
Bmw even do an oem connector kit to fit facelift tail lights on pre-facelift but all it does is what I shown you here.
