80 series ignition feed

Hi all.
I am looking for a 12V ignition feed in the engine bay of my 80 series diesel truck.
It is only required for energising a relay but I do not want to go through the firewall if I can avoid it.
Has any one an idea where one is?
PS. I have had a short poke around with a multimeter but had no luck.

there is a fuse box in the engine bay that has a ign side to it and a connector.

make sure there isn't a high drain on that circuit otherwise it could cause starting issues

I need the ignition wire to operate a relay or another wire that comes alive only when the engine is running.
This relay then powers a 12V feed to the caravan to keep the fridge running when in transit.

I do not have a fuse box on the drivers side that I can see, but there is one on the passenger side, but no ignition wire in there.
Here is a pic of said box.

It's activating a relay, hardly high drain.

Hook onto the charge fuse, It is the warning light part of the alternator wiring. It will come live with the engine running.
Or you could get a VSR

Yes I may have to look further into the charge fuse.
A VSR is of no use for running the caravan fridge whilst in transit I'm afraid.

Could you not use that for the trigger on a relay that could run the fridge ?

Seems I do not have this fuse box between the air cleaner and battery.
The 24Valve models must be different so I will have to look further into the charge fuse idea.
Yes I had a poke around this plug too with my voltage meter but could not find what I was looking for either.

It is all sorted and wired up.
I tapped onto the charge fuse under the fuse box. What a mission it was to get to it.
No pictures yet sorry.
The fridge operates from the truck now as it should.

Well it seems using the charge fuse was not the way to go. Driving to work i noticed the instrument lights for the turbo and the cam belt were glowing evr so slightly. I unpluged the feed wire fron the charge fuse to the relay and these lights went out.
I am now thinking I may have to either put a switch inside the cabin to manually turn this relay or find the ignition wire in there?
Back to the drawing board, humph.

Cheers guys. I will try my electronic relay first and if that fails, then I'll look at the ciggy feed etc.

Manual fuel pump?be ign to shutoff solenoid
,or ign to reverse /inhibitor switch wiring..should be a few others around..or just tap a ign fused feed on ign switch or from fuse box
