How big of a gauge of wire are we talking, and what for.
There may be other options.

 

2, 10 gauge wires for ham radios.

 

pull back a wheel-well liner and you'll find a big triangular grommet that comes out between door and dash with the OE looms passing through.

 

This is how I ran my light bar wiring.

It comes into the cabin by the drivers side footwell and the hood release lever.

 

Any pics of this.?

Considering a split charge relay from engine battery to charge a leisure battery that will be located in rear foot well for camping trips.

 

how do you vent that?

 

What about the grommet circled in yellow? Can that also be used?

I used the red one to run wire for an underseat subwoofer - it came out near the steering wheel linkage inside and I seem to recall was on kind of a weird angle to get the wire through (from the engine bay -- I fought with it quite a bit). However, the yellow one I seem to recall came out behind the middle of the dash and was an even bigger PITA to get to when I tried, hence why I just used the red one. That said, maybe it is easier to poke something through than the other, or if you're already tearing apart a lot of the dash.

 

I don't see why not. Pop off the cover and poke a dowel rod through there and see where It ends up.

 

Like @GeoJosh said above, this is behind the driver's side wheel well liner and the wires are easy to reach on the inside. I used an ice-pick to make the holes and you need to have the wire ready to slide in before you remove the pick as the holes seal up and are hard to find. Always check the inside of a grommet before poking the holes to make sure you don't poke anything you don't want to poke. The tight seal on the wires are water and dust tight.
