How would you get a wire from the frunk power supply to the subtrunk?

I just installed a 12v auxbeam switch to power some of my accessories. Would like that to include my subtrunk fridge.
Lots of different paths I can think of for this that’s I’ve done variations of but I’ve never run a wire INTO the vault or subtrunk.
Considering the bottom edge of the tailgate, the drain hole that functions as the vent, vault floor where it meets the side walls and so forth.
What do you guys think is the best (least painful to install also) path for this?

If you are needing 12vdc, that can be pulled from the 7 pin trailer Wiring. In my tests, the 12vdc stayed on even when the truck went to sleep. I have NOT tested this with low power mode.
Edit: this would keep you from running power from the frunk feed.

It’s true but my auxbeam controller is under the frunk tub and I want to be able to both switch it from the cabin and receive visual confirmation it’s getting power from outside the car.

I would probably explore drilling a hole through the bulkhead between the cabin and bed and put a rubber grommet in it (since it sounds like you already have power in the cabin). I've not looked into this but it's a path to explore.

…and possibly never roll your Tonneau again.

May require some very intricate routing…. And a wire coat hanger.

Also,.. don’t punch thru the Tonneau.

Obviously it would have to go around the tonneau path. But wires are not very thick.

I am also interested in this thread. I am contemplating how to install my Starlink HP dish on my @Urander bed rack (I think I have that figured out, basically...) , and where to install it's 120V power supply and router. I am thinking the vault will be the best place for them (instead of routing cables into the cabin), powered by an Ecoflow power supply (I have multiple of them), but having the Ecoflow power supply topped off by the Frunk 48V feed...

How about a small hole or gap in the gasket of rear window to access the back?

That is not a bad idea...but try to maintain a ‘seal’

still have to go around the Tonneau path… this is the tricky-est part.

it’s not a straight shot but may be easier then I envision at the height of the glass.

if there is already a cable housing low from cabin to bed, I would try to find that. Which may require pulling the bed liner panels (which may be a must already in general, depending on how clean of a look you are trying to achieve)

Cybergirl and myself had both routed wiring down the gunnels at the aerocover nearest the stainless steel so that the path goes from above and around all of the moving parts of the tonneau and into the vault.

A different path could be routed through the wheel wells along the Terrestrial armor rock sliders.

Not sure, but I think you need this while installing the wiring:

you're welcome.
