Power Access through the Firewall

[Big Tom]

Hi all, I have a 2021 Tradesman and I would like to add a Painless Wiring Cirkit Boss 70107 to it to get some things working in the Cab. Having only one power outlet is very limiting.
How do folks get wires through the firewall? Is there a knock out somewhere that I can't see?

Got it. Clutch delete plate.

Yep, great spot to use. Not good for much else nowadays
