    I’ve read that there is a pass through in the passenger side of the firewall and there should be a vent in the rear wall. You might have to remove the trim behind the seat.

    Try doing a search for firewall and see what you can find.

    I am not at my truck now or I would take a picture , but passenger side firewall, the is a 1/2 inch grommet that I ran my power and coax through… it is a little high up the firewall but sealed it with silicone to keep water out.

    Driver and passenger side have grommets with wires passing through them. I believe you still need to poke a small hole in the rubber grommet to get your cable through. I have wires passing through on both sides of the truck. My GMRS antenna cable goes from the center console to the passenger side firewall, up to my roof. Power comes from driver side firewall up to the center console (where my gmrs receiver is mounted).

    Where are you mounting the antenna ? That will determine everything

    Mag mount on top of cab, so it looks like vent behind back seat

    I'm doing it this way.

    He has a companion video that explains about the hole in the fire wall.

    My coax comes through a grommet under the drivers seat which is where my radio lives.
    My power was fuse tapped but Toyota had some issues with that. They shouldn't have, but they did. Now I'm looking at adding a secondary fuse block under the hood and running out to there. Will go back and watch the video on how he did that.

    This is what I did but my radio is mounted over the wireless charger because I don’t use that. I ran the antenna cable through a small grommet under the drivers seat and routed the wires under the seat and center console.

    That's where the radio head unit for mine mounts too. Main body under the seat but display under the chin of the dashboard in that cubby. I ran the control wires along the same path.

    I'm changing thing up a bit. I put a Pop & Lock with the wiring running down the left side and into the cab. This is why I wanted the antenna lead on the right side away from any electrical. But, the right side is awfully close to the exhaust. So here my thinking. On the rear wall of the cab there appear to be three rubber plugs. So I will use the center one of those to enter the cab. I'ts a straight run up to the sopt where I intend to mount the radio.

    If anyone happens to know the size of the holes I'd appreciate it before I start taking the rear of the cab apart. It would be a bummer to find out they are too small.
