13OutlanderSport Run Amp Power Wire?
 

Vehicle: 2013 Outlander Sport
Pyle 7" single din flip out head unit installed using Metra Dash kit
-Airbag service message appeared. I am seeing this is a common problem with aftermarket head unit installs if you don't disconnect the battery before pulling out stock unit. have to make service call with dealer to "reset" the airbag module. If you have further info that would help much!
NOW THE DILEMMA
I am trying to run the 2G power cord for my amplifiers into my cabin and I cant seem to find a grommet through the firewall.
Ive seen on other threads about the grommet behind the fender but this leads into the door and I don't know how to get the wire inside of the cabin.
If I have to drill... where is my babies sweet spot so I don't end up with a mess.

semi resolved
 

I found the MAIN wiring entrance right behind the motor that comes out behind the head unit and ran the wire through the outer edge of the boot. I will reseal with silicone to keep it watertight.
pretty sure this wont cause any interference with the factory wires in the bundle but I guess I wont truly know until it is fully hooked up.
Any additional info will help.

Is there a passenger side airbag status light on the factory radio bezel? I found on my full size Outlander that the harness on the radio bezel needed to be plugged in for the service message to disappear.
