Passing wires through Fire Wall?
 

I'm trying to wire an Escort QI45 in my E63 and am having trouble finding a passage for wires through the fire wall. I think it might help if I could take off the cover on the left of the dash when the door is open, but can't seem to get that off either.

Any ideas? Thanks.

wire it into the cigar lighter wires.but if you have a 2010 then thats pretty complicated. i think there is a fuse box on the left side of the dash. that just pops off with some force.
