2024 Tundra - Where are the usable grommets/passthru's from bed to cab?

I am starting this as a new thread as the older ones on passthru/grommet locations dont appear to work for the 2024 Tundra's.

I am attempting - and have not been successful yet - to find a passthru/grommet from the bed to the cab so that I can install a coax cable for a (insert your favorite device that needs coax here).

I have found some grommets that looked like they would work... Specifically, there is a grommet on driver and passenger side that can be seen from the outside on the back cab wall - just above where the bottom of the rear door is. This grommet does not appear to be accessible from in the cab. Oh, dont drop your pen light in here either, it takes a REALLY long time to fish it back out via that 3/4" hole. Dont ask me how I know.

Aside from that grommet, all others that I have check all appear to lead to dead space not reachable from in the cab.

On a 2024 Tundra, has anyone successfully found a path from bed to cab that doesnt require making any new (ie no drilling) holes? If so, PLEASE tell what that path is.

If there is no viable path, I will probably run the (very thin) coax thru the over-pressure vent on the cab back wall... but would like to not do it that way if there is another path.

 

I ran auto side step wiring through the wiring boot / rubber under the passenger front seat.

I ran the bed camera relocate through the wiring boot / rubber under the passenger rear seat.

Did have to poke small hole to feed wiring through. Used Marine caulk on both inside and outside of the boot to seal.

Both easily accessible.

Don't know if that helps at all.

 

Well... after hunting all around and not finding a suitable grommet and wanting to make any holes (that werent already there), I finally decided to run the coax via the over-pressure vent in the back.

How I did it (some after pictures, sorry, was focused on getting this done so no before pictures.)

1.) Removed both panels from behind the seats.
2.) released the tabs holding the over-pressure vent in place, popped it out, wedged it in place so it would be easier to pop back in later.
3.) Nice BIG hole to run very thin coax thru... ran the coax, figured out about where it would cross the threshold from outside to inside
4.) put a big piece of padded (foam) tap on the edge where the coax crosses, laid coax over it, put another big piece of tape over the coax to keep in it place.
5.) Popped the over-pressure vent back in place with coax under the bottom edge of it/under its outer rubber seal.
6.) coax fed under back seat into storage area for later.
7.) put covers back on.
8.) Now just need to figure out where to put radio.

Nice! I’ve been investigating the best way to get my coax out of the cab and up to the roof of my topper. Thanks for the pics. I have also been deciding where to mount my radio. Leading candidate is in the center console out of sight. (All radio controls are on the mic). Next challenge is finding a firewall pass through on the passenger side of the bay…

 

Funny you should mention getting power thru the firewall... that was the weekend project.

to add to the above antenna how to, this is what I did for power (sorry, no pictures on this) on 2024 Tundra SR5:

1.) Remove battery - as my hands are too big to fit through the small opening to the back side of battery
2.) behind the battery there is a big grommet that passes thru the firewall and is (easily??) accessible from front passenger side - just pop off side panel and under dash panel.
3.) On this grommet, there is a tube/nipple protruding from it, but it is sealed off. I cut the end off, tube is then open/passes to the inside.
4.) Paired up my red/black wire and fed thru hole. left just enough by battery to make hook-ups when rest was done.
5.) Ran wire in door-sill channel (those panels just pop right off) to back seat storage area.
6.) Fed wires under storage and thru back opening (pop off that flat panel) to where I bolted radio to storage floor (back passenger side).
7.) Connected radio end;
8.) used some "form a gasket" from autozone to plug hole were wires were fed thru - so there shouldnt be any leaks
9.) put battery back in, connected battery end.
10.) Mounted face-plate to a goose-neck; goose-neck mounted to bolt on front inside passenger seat rail
11.) Ran cables for remote speaker, face-plate back to radio
12.) Done

In hind-site - this was really easy (IF I had to do it again), but was hard first time thru as I didnt know where/how I was going to run stuff and how accessible stuff was/wasnt.

 

Awesome, thank you. This is exactly what I was looking for. I’d prefer to run the power on the passenger side for a couple of reasons. First, it will allow me to use the wiring provided by Midland without having to extend the length. Secondly, the driver side penetration has just enough room for one more wire set and I’m reserving that for the switch needed for a future light bar. I appreciate you sharing!

 

Currently doing something similar, this weekend I am running wires for a light bar that I’m installing on the rear half of my cab. I watched a few YouTube videos, but I found that where most people running wires was just through the air vents. I decide to just run the cables through the air vent on the center rear of the cab. I’m not sure what issues this is going to cause, if any. However, I will keep you guys updated currently what’s going through my head is that I can simply just tape off one side of the vent where the wires are coming through and then I still leave the rest of vent able to flow and open properly.

also, I am developing currently a product that would allow people to mount light bars, pods, LED lights whatever, On to their pick up without any drilling required. Would like to hear your guys’s thoughts on this if anyone reads this. Would you mount a light bar you could easily remove and that wouldn’t cause you to drill or screw anything to your pick up?
