Easiest way to run wires through firewall on passenger side?

[RKCRLR]

I'm looking for the easiest way to run wires through the firewall on the passenger side of my 3500 Hemi. Any suggestions?

Driver side but very easy and very clean

@NHOverland makes a grommet kit that goes where the clutch master cylinder cover plate is on the fire wall. That’s what I used.

Unfortunately that is for use on the driver's side (I'm assuming). I'm trying to avoid routing a wire from the passenger side under the dash over to the driver's side, through the firewall, and then back over to the passenger side under the hood. I'd like to go directly through the firewall on the passenger side.

Does anyone know where the fender mounted radio antenna wire ran through the firewall? It think it is still used on some C&C trucks. Perhaps there is still a hole there (or I could make one in that location if it was on the passenger side).

Edit: I found a video that shows the cable running through the front passenger door jamb between the hinges. Sure enough my truck has a hole there with a plug in it. While not perfect for my use (I was looking for something closer to the windshield) it is better than running the wire to the driver's side and back. If anyone knows of another way I'm still interested.

A drill bit and proper rubber grommet?
