Is there a diagram of firewall plugs?

Wondering if there is a diagram of where the rubber grommets are located in the firewall (and perhaps also under the cab) for a 3rd gen. Does this even exist?

All I saw on my 2019 Sport access cab was one under the lip of the brake booster on the driver side, and one at the same height and location on the passenger side. There's got to be more...both of those are stuffed full of wires and I need to drag my new ditch lights switch through there. TIA!

 

Go through the grommet beside the main harness. It comes out just above the brake pedal. Lot of room, I’ve got two harnesses and a vhf run through there.

 

Is that lower and more center than the one just under the lip of the brake booster? I have a 4AWG wire going through that one, too big to fit anything else. If there is another one further in to the center then that would work but I can't see another.

 

The main harness goes through the middle, but you can put a slit on the side and put it through beside. I put a PL-259 through there, you will be fine running bare wires.
