Cable via firewall - best access from engine bay to cabin

[Californication69]

As per the thread title.
what’s the best access through the firewall bulkhead ?
Is it still the same Gromit behind battery or is there somewhere else to pop 2 or 4 gauge 14 wires through ?
TIA

Hoping someone has some useful information on how I can get some cables for lightbar into the cabin from the engine bay ?
I might have to grab a 16mm flat drill and just cut me a new hole

Follow some existing cables?

Any use? 12 or 17.

Remove the battery and the cover to the E-Box and you can follow the main loom.
Be careful not to use the grommet that is actually a drain.

Absolutely! So there are 4 entry points, I will have to see which is the most accessible from inside the vehicle. Thank you

Not really wanting to remove the battery. Does it not cause strange software gremlins to creep in ?
And thank you for the heads up on the drain grommets. Had enough of those pesky things whilst fixing a golf sunroof blockage that had 3 inches of water inside the Sons car! I’ve heard the California has right angle connectors at the roof level, not easily accessible, so I most certainly do not want to pull or poke a hole in those drain tubes & dislodge ! Thank you @Loz
Do we have access to system diagrams like on the T6 forum? Are they in the VIP section ?
