Cross post from the GT3 forum. Guide shows how to permanently wire your battery maintainer so you don't need to deal with where to run wires under doors or which outlets will stay live.
I have my plug coming up through the rain try cover slit which makes a really nice install.
When not in use the little plug just tucks into the slot.
What slot? Do you just shove it under the cover? I didn't want it just dangling around in there and thought the inflator box was perfect to keep it secure.
Simple mod that takes only a few minutes. You go direct to the battery with your leads from the battery tender and the connectors exit where the right front fender and the a-pillar meet. Feed the cable under the black cover for the windshield wiper mechanism. Easy peasy and you don't have to deal with using a 12v outlet inside the car or running wires past door jambs. Also, should your battery die completely one day, you can get 12v into the system to open a door, frunk lid, etc the easiest way.

Literally was going to install mine the exact same way this weekend.
Just FYI, if you do decide to use the in-car port, Suncoast recently this note about keeping the plug socket alive on their web page about the maintainer. :
981, 991, & 718 - For 2013-2018 Boxster, Cayman, & 911 Carrera models: Long term storage can put these cars in "Sleep Mode", which will disable the center console plug socket and shut off the battery maintainer. To bypass this, lock the door after setting up the battery maintainer. Or directly connect the battery maintainer to the recommended charging points using the optional alligator clips.
Good idea and most every motorcycle owner does the same thing, and it was what I planned to do. You can use a Deltron Battery Tender that comes with the connectors, etc. for a fraction of the price Porsche charges.
Would be nice if they simply made a “plug in” attachment or magnetic attachment like Ferrari has. It’s not rocket science and for the prices they charge it’s a no brainer. Disappointed that Porsche doesn’t produce their cars with it.
I had the hard wire done in a previous Cayman, but learned that was a big mistake for someone that can be as oblivious to his surroundings as me.
There were a couple times I forgot all about it (it isn't that obvious when dangling off the corner of the window on the passenger), and proceeded to back out of the garage dragging my CTEK.
Finally decided to scrap the hard wire, and went back to using the cigarette lighter, which I couldn't miss. I use the cigarette lighter on my 911 now as well. Really no harder to plug into the receptacle, and it's a lot safer.

I use the cigarette lighter, too. Very easy to use. I have never had a shut off issue, either - as soon as you open the door the car “wakes up.”

I keep mine unlocked and have never had a sleep mode issue - and I have had mine on the CTEK for weeks at a time, no problem.

For sure. I have a direct to the battery connection on my motorcycle too! The Deltron charger I use charges at a higher rate if needed than the Porsche by CTEK unit which I also have. I hang a little keychain on the dummy key so as to not forget the charger is connected. Anything hanging there or on some other obvious location in the car will work. I also like I can use the battery tender with any of my vehicles. They all have a pigtail direct to the battery now.

Instead of having the wires draping down the side of the car with the maintainer on the floor where it may not be seen, I have the battery tender mounted high on a wall with the wire dangling from the wall into the frunk. That way it is easy to see as you get behind the wheel. I have read where others have put a sign on their windshield when they connect their maintainer to remind them.

This is a good idea. My home is leased so the fewer holes I punch in the wall, the better. Plus, I use the battery tender for other vehicles, not just this one. Even with your setup, you may consider having something you can't ignore on the inside of your vehicle like a type of "remove before flight" tag on your dummy key. If you are in a rush one day, you may forget you're connected.

this is why I made up a piece of paper that says "Battery Tender Connected" and put it under my windshield wiper when I hook up the unit....
