I'm about to install my meth kit, and I want to run the wiring into the car along with my WB and vacuum line for the vac/boost gauge. I've heard of people using existing areas to feed wires/etc. into but I'm wondering, since I have so many, I may just be better off drilling a new hole, put a rubber grommet in and running all my wires into it for the interior. If you suggest this, could you post any pics or how to's? Thanks.
