Running Power Wire Thru Firewall

[Sbeppel]

Help! I know it's been covered, but I am hoping for some pics. I have a 2014 HB. Looking to install a powered subby and I can't seem to see where to get the wire thru. Do I need to remove the battery? Any help would be appreiciated.

I've googled and the 2014 LE engine bay looks slightly similar to me old 2008. There should be 2 big rubber gromets on the left and right of the firewall. Choose one.

There will be a big bunch of cables coming out and beside it on the left and right of the gromet are two rubber towers coming out? cut one of them and spray some silicone greese and run your power cable there.

i ran mine and it fits a 4ga wire easily.
