Hi, i've been given a set of these lights ^ for my 94 318iS but the car their from has a third brake light and my car hasn't.
The problem is that the passenger side brake light and back light doesn't work, but when i swap them round they work, i think it's because i have no third brake light and no check control, (swapping i mean drivers side on the passenger side and vice versa and then they work),
but when i put them back the passenger side doesn't work
is their a way around this, like running a wire from the drivers side along the trim to the passenger side or a way of getting round check control.
Has anyone had this before and how did you get round it.
Thanks in advance
