Littelfuse FHZ busbars used in the Grenadier

As I understand it, yes.
The question is how I can connect the rear 12V connection to the auxiliary battery. According to the manual, the 12V connection is located on the fuse box in the cockpit. This fuse box is powered by the cable with the white tape. I connected the cable with the white tape to the auxiliary battery, but the 12V connection still drew power from the starter battery.

I suggest the easiest option is to add another 12v socket wired to the auxiliary battery.

That's what I did. But I don't think it makes much sense to install a connection when there is already one available. I think it would make more sense to find the cable that goes directly to the 12V connection and then connect it via another fuse box that is powered directly by the auxiliary battery.

That is what I did. One to the rear of the car for any trailer or caravan and another to power outlets in the rear next to the drawers. Both off the aux battery on a fused circuit.

OK, that's probably the option we should choose, as it doesn't require any changes to the existing electrical system. Thanks for the quick replies!

I may need to revise the post.

EDIT: the cable is red with a green strip and also yellow tape. Second from left. Are we both talking about the same cable to the PDM?

Yes I believe so
