2007~2015 Run Wires Through Firewall

:
2009 Mazda CX-9 GT
Searched but didn't see anything. Anybody run wires through the firewall? Any grommets or holes already there? Did a quick look but didn't see anything that jumped out at me. Just need something small for two 14ga wires.
 
:
13' CX-5 and 16' Mazda6 both Touring w/Tech/Bose
On 2016 Mazda6 there's a rubber grommet with cables running through the firewall behind the pedals.....in the engine bay side I think there was a nipple. Actually can't recal if nipple was in the cabin side or engine bay side...Regardless look for the nipple! Snip the nipple! Run cable through nipple. In my case I then used electrical tape and velcro tape the secure cable/close the opening.

There is a wiring harness that goes through the firewall behind the battery. You can punch a small hole through the grommet there.
