Fiat Ducato x230 2.5tdi 1999 - split charge fuse

[Jev88]

Hi.
Model as above. Where are the fuses for split relay charging? Thinking of adding battery to battery charger but will need current connection disabling?

I have chunky red wires going to two fuses mounted on side of engine bay very near battery (driver's side) .

How will I know if I have pulled correct fuse anyway as I am told trickle charge to leisure battery will be minimal anyway with engine running on existing system. Current wires to control panel in rest of MH must be okay as fridge runs 12V switch with red light when engine running. Will the split feed be linked to this same feed do that I can use fridge switch as feedback to know if I have disarmed it?

Should anyone else with this age of engine be looking I think I have found it.

In line fuse straight from Positive battery post on green wire.



I would still like to know what this chunky connection is for (green box)
