This evening's tinkering was on fuse box underneath the glove box. The three empty fuse slots are constantly powered, they would be a perfect place to fuse tap in for a Dash Cam with a parking mode. The Kenwood cam I'll be using will solder into the Kenwood Head Unit's harness.
Interior cabin lights (DOME 7.5A fuse) are constantly powered. After twenty minutes if the ignition has not been turned on the lights will switch off, however, the fuse circuit still has power and could also be tapped as a constant power source. I'd just stick with utilising the empty fuse slot personally.
Playing with orientations of the fuse tap revealed that the supplied fuses that arrived today are really quite garbage. The coloured plastic separated from the metal when I pulled them out from the fuse tap. Hardly a shocker given it was cheap eBay crap. I'm satisfied with the quality of the fuse tap itself, but I'll be popping back to Jaycar for some decent Low Profile Mini Blade fuses for peace of mind.
