Looking for some help with my 991.1 (2013 4S Cabriolet), I've installed a backup camera (w/ Joyeauto). I ran power to the passenger fuse panel and have it plugged into a "Not Used" open slot, but think this is a constant on slot, creating a parasitic draw. Does anyone have any info on the fuse panel slots that are ignition activated vs. constant? I only drive her a couple times a week and I've had the battery run out a couple of times.

my 2017 C2 doesn't have PDCC so I used that slot as it is ignition only, however there is only one tab for power so you need a separate ground connection, there are plenty of nuts and blots close that work. haven't had any problems there. if you have PDCC you could just use a fuse expander for the connection and won't need a separate ground.

Use a simple volt meter and see which slots are hot all the time and which ones are only hot when the ignition is on.

This tool from Amazon by the way made finding the right fuse spot to tap into for constant vs. switched power made it very, very easy.

Note that (some) circuits look like they are powered all the time when shutting the car down, but cut out after 6 minutes (I timed it). The cigarette lighter socket for example.
