I'm confused

[chrsbe]

Who has dug deep into the fuse box under the ignition key? I need your help.

My Wolfbox is currently connected to fuse FC23 using a piggyback fuse tap. When the PWR switch in the overhead switch panel is turned on, the Wolfbox powers up as well. I would like to change this so that it only receives power when the ignition key is turned on.

Which fuse should I use instead?
Merci beaucoup

FC12 should work.

or 21, as I think the center console outlets are ignition only

I've been meaning to adjust mine too let us know what works out for you.

I used 22 (USB) - it was convenient and accessory-controlled.

I'll insert a file note that the cockpit fuses can vary slightly according to the distribution region. The layout might also vary with the MY so refer to your fuse card as the primary source of information.

This is the fuse card for my AU delivered MY23:
- The blacked out fuse number positions are not wired.
- FC10 is omitted (no e-call).
- Positions FC18 to FC23 are accessories fuses (power with key on).
- Positions FC10 to FC17 are live fuses.

I'm using FC12 (head unit) and FC23 (rear 12v outlet). My Wolfbox also comes on with the PWR switch because the rear 12v outlet is active with the PWR switch on. I push the power button on the bottom of the mirror to turn it off.

They sell a lead that plugs into the obd port. No piggyback bullshit.

One point you may want to check is whether the (likely small) Wolfbox wiring gauge is appropriate to blow a 30A fuse in a case of fault if you directly connect to it.

I'm not quite following you there.
I have a fuse tap in those two slots. The fuse ratings for the headunit and 12v outlet are unchanged. The fuses facing the Wolfbox are 7.5amp so a short to ground on either the constant power or ignition power circuit will go open circuit at ~7.5 amps maximum current.

Should be easy to follow...
_If_ you (sb else) have an additional low-amperage fuse towards the WB: Fine.
If not, and you (or sb else with no deeper knowledge) connects sth like the the WB directly with a low gauge wire assuming he's "fused" by the e.g. 30A, then there might be a problem.
