Been searching through google and CL but nothing is coming up for the answer that i need.

I'm pretty sure I am over thinking the concept but I cannot find pictures of routed air lines through the body of car, do people drill out holes in their trunk and wheel well? Or are you guys going through factory holes like the wiring grommet. Reason I am asking is because I don't want to drill unnecessary holes that I don't need. Secondly for the wiring for the E-Level sensors are you guys drill holes for these as well too? Sorry for the dumb question but most search i've found were only mounting E-level and trunk setups not actual Air hose and wiring placement. Thank you in advance.
