Gauge Pod Advice

[Thrust]

Ok I am installing a gauge pod with a single gauge. I need to know where to run my vacuum source and O2 sensor wire from the cab to the engine bay. I think I saw something in the past about running items through this grommet? See picture. The second picture is the connection i am needing to run to the cab. ¹The hood release is right next to it and I can see where it goes between two interior panels that fit against the firewall on the inside.
Is this the best spot to run the wires?
Or have others used something else?
Gauge is an Innovate PSB-1.
Thanks

That’s where I run all my wiring through id go for that just drill or cut you a lil hole in it I actually used a big thick screw driver to punch a hole through it since there’s rubber on the inside of the cab too and just putting a slit on the engine bay side is hard to make a precise cut on the cab side and get it to line up properly
