Running cable through firewall

Hi guys just wondering if anyone would know where would be best to run a 0 gauge cable through the firewall. If it helps it's a 99 GU 2.8 manual. Thanks

wow that is very large. Only spot i can think of (viewing from an 3.0L) is behind the engine is a bunch of wires (harness pack) that goes through a large rubber pod that you could cut open on top and feed through. Not sure if it would be quite big enough though. Where are you trying to get it to?

Thinking like Scotty, but why so thick????

Yeah the wires overkill back in my younger days I ran a big wank factor stereo which required it. I'm now more mature (cough) and the wire is sitting around collecting dust and I want to run power to rear of car for stuff and thought instead of buying new cable. Might aswell reuse what I've already paid for kinda thing

Fair enough, why not run it along the chassis rail and come up through the rubber grommet under rear 1/4 panel?

That sounds like a plan. Basically going to run it to rear then I have a distribution block which will take 0gauge in then has about 5 4-8gauge outs on it. So will put plugs in for fridge/Anderson plug. Cigarette lighter just the usual stuff. Another question I hear lots that the earths are terrible. What would be easiest way to better the earths. I have plenty of this 0 gauge so might aswell upgrade earths too yeah?

This is slightly dodgy but you can run it through the holes in the back left top corner (passenger side) of the engine bay and tap into the large grommet that runs the wires for the passenger door into the vehicle. Then run it as normal inside...

I can assure you that the door will not be in the way of the wire, just make sure there is no slack from the engine bay into the vehicle as you are making a slightly curved set up.

Great use that cut out on the left hand side in the back, Things in there to cable tie Dist. block. your right sounds like a plan, keep us updated

Cheers guys. Damn you all for the quick replies. Now I have no excuse to get comfy on the couch

agree with the rear quarter panel grommet. that is where i was heading with my question. large plug there.
