EMI-pass through wiring

[Tbone]

I'm running my wiring thru the firewall and was curious if I need to separate this wiring bundle:

Magneto wiring (shielded)
Fuel flow wiring (red cube)
Oil & fuel pressure transducer (Dynon)
Ammeter wiring (Dynon)
Manifold pressure wiring (Dynon)
CHT & EGT probe wiring (Dynon)

I think that these items can be ran together through the single pass through. I'm trying to keep the penetrations at a minimum. What are your thoughts?

If it were me, I would run the Magneto wiring (shielded) in a different hole than the other signal wires listed above.

20-years ago building my RV-6 I also wanted as few holes as possible. I ran the shielded magneto wires through the same hole as the battery/alternator/starter wire went through.
