Constant 12v fuse for dash cam?

[ChefExcellence]

I'm looking to hard wire my new dash cam into my DS3 but I need a permanent 12v fuse so I can use the parking mode - Does anyone know which fuse will be always live (even when the engine is running?)

[Chris_Blue]

No. Sorry. Can you not just run a live straight from the positive terminal of the battery, with an inline fuse

That's what I did for my aftermarket air horns

I did try but couldn't for the life of me get the cable to go through the grommit on the firewall
