Well I finally got my cameras installed.
Went with Viofo a329. I had the pre-wiring also for the Porsche cameras. I was able to, with some modification, use the video feed wire to connect to the rear camera. It only needs this cable and not a power source much like the Blackvue.
The fuse...
Thanks for posting all of this @Degenatron
I haven't found a fuse that switches off after 30 minutes yet. I'll have to explore more. I did do the pre-wire so I'll sadly probably just end up using that.
Also, I blew that 1 amp fuse in the passenger door side fuse box. Good lucky finding a 1...
My guess is that the front end fuse box is in the frunk area.
I posted photos from the front pax footwell and side panel and the rear trunk panels.

Thank you very much for posting this. I'm guessing the fuse in the passenger side footwell is always on (being that the overhead harness has a switched 12v and an always on 12v) and there is a relay somewhere after. I'm testing with a multimeter as we speak.
I had a harness but it had not...
Well nothing in the front pax side that I could find powered down after 30 minutes. Trying the trunk next. I would really like to find where the 12vdc port goes to from the back and the front. There has to be a fuse hiding somewhere for that. Where might the 4th fuse box be?
Actually had a semi big brain idea to close the latch on the pax side door and lock the car while the door is open. Car locks. Turned the alarm off. Going to wait 30 minutes and take a multimeter to it. This should allow me to find the switched fuses without too much time. Hopefully they...
Hopefully they are willing to share.
In the meantime I'm going fuse by fuse and waiting 30 minutes for the car to shut off. This is going to be fun.
So lovely that Porsche decided to not give us a fuse diagram...
Found the back fuse box. Looks like they are all active, however, I was testing with doors/tailgate open so perhaps they don't switch until these are closed? I have yet to find a switched fuse. I'll keep looking when I have more time.
I haven't found the fuse for the 12vdc outlets. That is...
Yeah don't ask me why I'm worried about it now. The Texas tag is a flat stick the size of a credit card with really strong adhesive. Just worried if I ever have to tear it off and replace that it might take some of the black with it and look bad.
For asthetic reasons I would like to put the toll stick where my radar suction cup is right now in the photo. My only worry is that it will pull the dots away if I ever remove it. Then again the dots really seem pretty flat.
So I was looking at locations for where I'm going to put everything (dash cam, toll tag, radar detector) and it looks like the dot matrix is flat despite being quite prevalant.
I'm a bit worried about sticking anything adhesive to the dot matrix. It almost seems like it is inside the glass...
I opted for the dashcam wiring. I also did this on my Cayenne but it of course has a proprietary harness which I have heard some 3rd party cameras have this figured out.
That being said I haven't figured the harness out and I despise pin taps for wiring.
