Glad to hear the power source worked for you!

I am currently using the horn, thanks for that info. As it works fine I haven’t checked other sources yet but will be looking into it. The fuse split sticks out far enough that the cover won’t close when using the horn fuse slot, not a issue for me but will eventually change it up

Okay, by 'constant power' - I presume you want power even when the key is turned off?

Try fuse F44 - it is the horn relay fuse. Since the horn always works with key on or off, it should have power.

You might also use a multimeter to look for power with the key turned off.....

sorry, I put it in the title but thought that would be enough. I have a 07 MCS (R56). The cigarette outlets are not constant power and I do not have the USB plug next to my aux. The big this is that I cannot find my meter atm, so I was hoping someone else has tried/done this. I was looking on NAM too and there doesn't seem to be any straight answers

You didn't mention what year and model MINI you have, but if it has a cigarette lighter, that might be a good constant power switched source. 

It may not have a fuse in the interior fuse box, but you can easily tap into the line.

Hey everyone, I am currently removing trim to run cables for a dash cam that I have coming my way. I am looking to hardwire to the car through the interior fuse box on the passenger side (the dash cam monitors parking if it has constant power). does anyone happen to know which fuse slots have constant power?
