Putting wires thru 2015 Silverado firewall

[Delta Hotel]

Hey y'all, sorry if this has been asked endlessly elsewhere, but I used the search function all over the forum and came up empty handed.

I have a 2015 Silverado Crew, 6.5 bed, 5.3, LT model.
Just added some Rigid LED driving lights and want them triggered independently thru a switch in the cab vs triggered by main or high beams, or fogs.

Thus I need to run 3, 16-18 gauge switch wires thru the firewall with minimum damage if poss.
There's a large rubber grommet next to master cylinder and I was wondering....?

Any help, greatly appreciated.

Thanks guys and gals! Great Forum, BTW!

Cut the nipple off that grommet or slice the nipple you see and fish them through. That is where I ran my power wire for the Kicker kit.

 

Be careful, sharp metal up under to the dash.

Thanks RAWYZF for the super quick reply!
So the big round grommet on the firewall to the right of the brake master cylinder (if facing truck head on) is the one, to clip or pierce the nipple that's at 12:00 ?

Use a coat hanger to fish thru maybe?

Thanks again !

You could also run it by the the door hinge. Much easier in my opinion, Thats where I ran the wires for my lightbar after getting to frustrated with trying to get them through the spot you guys are talking about. I can take a pic if you want.

Use the dedicated hole with the grommet by the door hinge. Through the fender & into the cab. Don't make an easy job hard.

I'd like to see pics of the hinge wires as well, for when I add lights.

Heres some pics. I wrapped the wire with some looming for protection and a cleaner look.
