Rear ACC power?

[llama000]

Hi all!... short time reader first time poster

I was wondering if you guys might be able to help me out. I've searched around this forum quite a bit and haven't found the solution to my problem.

Is there is any accessories power available in the boot at all? I've just wired up my amp with 2 rears and soon a 10" sub but I stupidly assumed that because the battery was in the boot there would be some ACC power somewhere around.

I tried that plug above the relay box to the left of the battery thinking that might be an extra that used ACC power but no luck

I know there is an optional extra for AUX power for a caravan which makes me wonder if there is an empty plug with 12V for it. And even if there is would it be constant or switched with the accessories.

I know the simple solution is run a cable to the centre console but I'm hoping someone knows an easier way because the way I wired the inputs and speakers was so I didn't have to go all the way to the console.

Are there any wiring diagrams available?

The car is an '07 Omega BTW

Cheers

I bought a genuine acc (lighter) plug from holden, was fairly cheap, it came with fitting instructions and goes in next to the battery in the boot where there was an unused 12v slot.
