Getting from cab to engine bay

I know y’all have done this
Looking for best spot to drill thru to cab to run many wires. I will grommet to protect.
Thanks

 

Any more after having fixed many mishaps .You name it people have drilled into it

I go through the floor and up into the engine bay as needed.

It takes more wire but to me lots less frustration and damage

 

I’ve used this on my last taco.
passenger side my 12 also has it

 

There is a grommet on the driver's side behind the pedals. Can only fit a few wires though. I used that until I could and then drilled a new hole right next to it.
Really anywhere works, as long as you aren't drilling into something, and have enough clearance on both sides.

 

I used that same passengers side hole for my in the cab breakout wire.

Also you can go through the main factory grommet or above it so long as you're high enough above the pedals like I did for all of my switch trigger wires.

There's ton of room if you're not a manual lile me and you can go through the spot in the cab where there's the space for the clutch lines.

 

I drilled a hole right by the pedals. And one on the passenger side. I’ll grab some pics later this afternoon.

 

I drilled a hole underneath by the brake booster to run some 0/1 Awg for my audio system or cut a hole in the main firewall grommet where most of the wires ran then resealed that with some black caulk to help keep water out
