2019 Cayenne Turbo fuse box confusion

I had a dashcam to install on a 2019 Cayenne Turbo. I needed a switched power source (ACC) and I thought I could pigtail off of something in the fuse box. I looked in the owner’s manual and found out that there was no fusebox on the passenger side which would have been closer to the desired dashcam position. So I went to the driver’s side and found that…

1. There is no legend or markings telling me the socket numbers
2. The fuses in the sockets don’t correspond to those in the manual

This happened on the 2008 Cayenne Turbo too. The “first year of production” models and their manuals don’t match up.

I couldn’t find a suitable switched power source anyways so I went to the fuse box under the dead-pedal. Same problem here; no markings and fuses are either missing where the manual say they should be or a fuse is in a position the manual doesn’t say there should be one.

Anyways, I made an educated guess and figured out that the middle column in the bottom row had to be “Row D” in the manual. I confirmed this by pulling the fuse from position #16 – Left headlight electronics. When I turned the ignition, a warning for “Left lo-beam…” showed up on the dash. The funny thing is the left headlight still worked without the fuse. It must be the automatic hi/lo beam sensor or some other PDLS feature unrelated to the regular lights.

So for those seeking a switched power source, you can use socket #15 and #16 (Right and Left headlight electronics). There IS enough height for piggy back adapters under the dead-pedal. If you’re using TWO piggy-back/add-a-circuit, BEWARE – the pigtail from #15 will interfere with #16. A little bit of plastic shaving/forming will be necessary. And no, you can’t flip one left-side-right either because the divider in the fusebox interferes with the piggy-back.

Good Luck!
