Z4M fusebox confusion?

Quick one from me, I was looking to pull the fuel pump fuses so I can get the injectors out for a clean and spotted something a bit strange which I can't find reference to anywhere else. Fuse #19 has a strange connector which appears to have room for 2 fuses but only had 1 5 amp fuse installed (not the same fuse design as the others either) which I've taken out in the picture.
Presume it's something aftermarket but no idea what, any one else have it or any ideas what it does or even have a fuse in #19? Presumably this is M specific as other E85's seem to suggest it's for the fuel pump but don't think it is on the M....
(I'd already pulled #33 btw just incase someone thinks its missing!)

That looks just like the power feed for my dash cam.
Definitely reckon that’s for an aftermarket accessory
 
Yeah, only aftermarket stuff I’m aware of is Denison ice link but 99% sure that doesn’t have a fuse box connection, and a Tracker which I believe was installed from the factory or close to...could be that...?
 
Would have thought wiring a tracker at the fuse box might have been a bit obvious for a thief.
Not previous had a phone kit installed?

No phone kit I know of apart from the OEM install. Reason I thought Tracker was I believe it has a battery and the hardwire was only used when the battery is dead so not totally dependent on it, could well be wrong though!
 
That definitely looks like something after-market.

I've just been out and looked at the fusebox in my MC and there is no fuse fitted in position No. 19. :thumbsup:

Ah yes very similar, can't see anything obvious it might be but guess does something important so I'll leave it alone!

Thanks for confirming! I'll just leave it alone and not worry about it then :thumbsup:

Cheers all!
 
I pulled the fuses for the fuel pump recently so I could turn the engine without it firing to build the oil pressure. It had been sat for a while so thought what harm could it do.

Ended up pulling 4 fuses before I finally isolated it. Annoying I have forgotten which one did it, it was another that is not identified on the fuse chart as related to the pump (19 and 33), so if you figure it out let me know for future.

Fuse 44 and I think Fuse 4 was te final fuse I pulled which did the trick.

Just Fuse 4 worked for me, the others don't seem to be the same as the non M's which is annoying as I don't have a fuse chart!
 
Thats what I used at first, but 4 and 44 are shown empty, so perhaps is for a non M car.

I then found this, which shows 4 and 44 next to the fuel pump image also

So it's fuse 4 for Z4M then...?

Just for clarity.

Well i tried the ones in the above diagram and nothing changed.

Pulled fuse 4 and engine died within a few seconds on my M so yes, it would appear to be so.
 
I think so from memory, 19 and 33 didn't do anthing, the car still started. What I didn't check though was would just fuse 4 removed stop the fuel pump as I pulled all 4 one by one, 4 being the last one. If in doubt pull all 4.
