FWIW, from the MY 2019 and on, the main fuse box for your accessory power in the Cayenne is under the plastic dead pedal. Middle column on the bottom is "Row D", particularly the bottom two vertical slots with identical 20A fuses (No. 15 & 16) control right and left headlight electronics for PDLS features that are only available with the ignition ON. You may piggy back off of them with an ATO sized add-a-fuse to gain 12V ACC power. There IS enough space for two adapters, but the grounding tail of the adapters may interfere with each other when installed side-by-side. Unfortunately, there is a plastic divider that will interfere if you flip-flop the adapters. Minor plastic shaving of the pigtail is necessary. Beware, the NEWW Cayenne uses a LiFePO4 (Lithium) battery that is sending 48V to onboard equipment. DO NOT splice into an existing power cable until you've taken a meter to it.

Black mini, great photos! How does the MOST-HUR handle the turn-off delay and door open? Does your navi unit stay on after you turn off the engine, then turn off after 60 seconds or so? When you open the car door, does the navi unit and the interior lights go on at the same time?
Thanks RFM, I see. The evaporator and heat exchanger is right above the left rear wheel. I'm guessing those two things need air-flow. That means I shouldn't permanently cover up the grill with anything - like a subwoofer enclosure.
Here's a question for fellow Cayenne owners. I noticed that there are three different kinds of finishes on the left wall of the trunk space by the rear wheel well. 1) A plastic grill on the lower part by floor. 2) A pull away lid with nothing inside the wheel well. 3) A plastic catch-all bucket a la mini-van. Does anyone know what's behind the grill of the first version?
I finally got to get the photos off the phone camera. This is the only drain plug for the engine oil. Notice other pipes where second plug would be on V6 vehicles. This is the oil filter housing. Bottom of photo is front of vehicle. Notice the two fabric wrapped pipes that is in the way of accessing the filter cap. This photo was taken BEFORE removing the cap. Also, there is a aluminum sleeve for the bolt shaped like an hour glass when you remove the bolt holding the fabric wrapped hydraulic line. Don't lose it.
Today, I changed the engine oil and filter on a 2008 Cayenne Turbo with 9400 mi. I've seen photos from other contributors of their oil change procedures for the V6 Cayenne and was expecting exactly the same thing when I creeped myself under the car. When I removed the plastic panels from under the car, I was confused. This car only had one drain plug and the filter housing was on a 45 degree slant towards the passenger (right) side covered by a U shaped hydraulic line. It actually sounded the same as Dutch's Transsyberia write up: http://www.renntech....ria-oil-change/ The space around the filter assembly is very tight - not enough to put a zip-loc bag around it. Might have a better chance making a shield out of a milk carton to deflect the oil away from other parts. I didn't do either and I was cleaning for at least an hour. On the bright side, the under carriage is immaculate now. The filter casing is huge with a big hexagon nut molded on it. I don't think the filter wrench for the V6 Cayenne (000.721.920.40) would work. There's not enough space for a strap wrench. So, I used a pair of 12 in. ChannelLock pliers. And what surprised me the most. The Turbo took 11 quarts of Mobil1 0W-40 oil! I am so glad I bought a dozen bottles. All in all, it took me 4 hours - doubting myself against everybody's photos for a good 2 hours.
Vehicles with PCM 2 and up will not have ACC power behind the head unit. It uses the CAN-BUS network to activate on ignition. You'll need a CAN-BUS adapter or a manual toggle switch.
