Okay, my friend and I were doing a stereo install on his car when we ran into a problem. We were attempting to run a 12 gauge wire to his doors because his stock speaker wiring has since corroded and on the verge of breaking. On my car, a 1997 Eclipse, it was easy, i just ran it through a rather large hole near the interior fuse box to the doors. His, however, has a large plastic cap with screws over where my hole should be. It looks like a holder of some sort that holds the connector for the power windows, door locks, mirrors, etc. I was wondering should we take this plastic piece off, remove the connector, and just connect the two harnesses without the large plastic router or cap?... whatever it's called. Also, if we were to do so, there's absolutely no way i could unscrew it from the passenger side because the one on the passenger side has a rather large object (either the airbag or the heater core, i'm not sure) in front of it, preventing the use of a screw driver. Also, are there any adverse affects that he may face because of the the the plastic holder/piece's absence? Any information on if i should remove, how i can remove, and what this plastic connector holder/router is would be greatly appreciated. Also, any ideas as to how we should run the wire is also welcomed. Thanks in advance for your assistance.
