Isolation switch on diesel?

[Bryce]

I'm looking into fitting a isolation in my jx as it drains the battery (think it's the radio) after a couple of days.
I've got a one on the battery in the engine bay but it's a pain to get to with the drawers and awning sitting on top of the engine lid.
Had a quick search and it seems it is more difficult to fit up front on a diesel? Can anyone point me in the right direction of how to go about doing it?
Cheers

make up a bracket and have this behind the number plate flap disconnecting the earth?

I can't believe I hadn't thought of that! Just got so focused on the idea it would need to be in the cab. Cheers will have a look into where it could be fitted

The main fuse panel has a single power feed.
With one big spade on the late fuse panel. You can put a switch inline that wire without any irreversibile modification.
