Tapping fuse 42 or 45 for a 12V accessory?

I'm installing this Inclinometer for my T4R.

Planning to use a mini-fuse Add-a-circuit Tap to power it. Now just deciding on which fuse to tap into.

The amp rating for this device isn't rated, but I'm thinking of going for a 10A fuse (similar to a dash cam install).

Looking at my interior fuse diagram , I'm thinking of using either
  • Mini-fuse 42: (SECU/HORN) Theft deterrent system
  • Mini-fuse 45: (CIG) "No circuit"


I assume 45 is the fuse for the cigarette lighter socket, but what is up with the "No Circuit" description?
  • But the 7.5A fuse 44 "ACC" is also marked with 12V icon

Anyways, I typically have a fair amount of devices powered/charged by the cigarette socket, so I wouldn't want to overload it.

Any suggestions on which fuse to use?
