. Can you point me towards something that shows where I can find this connection on a 2016 AP1 Model S?
Shows? No, I don't think there are any pictures posted around here. But I explained earlier. Its on the right hand side. Remove the glove box and you can see all the Fakra connectors going into the AP engine. You won't find tag or labels to show you, but study it a bit, then look for one that is running from the left side of the APE towards the A pillar/right side of the car >toward the door hinges. You are in effect tracing it backwards toward the rear of the car. That where/how you will find it. Keep in mind, Tesla didn't put these cars together with us wanting to take them apart later. They are not concerned with marking stuff to make it easier for us. So we share.
After you find what is likely the right rear cam cable, trace it to the APE and you can unplug it. If you have the rear camera on the display, when it goes blank you know you found it. Study those Fakra connectors. Notice how the purple clip springs down, to allow it to be unplugged? You must do that to unplug these cables. Some are so hard to reach, you may need to unscrew the APE to get to the cable. I've lowered the APE a couple of times. Most of the time the fans on top of the APE have been running too, because it was powered. Its not for the faint of heart. If you are going to unscrew the APE and lower it for any reason, I highly recommend you at least, open the right side door, and let the car sit for about 10+ minutes until it shuts down on its own, call it going to sleep if you wish. Then the APE also is in a safer condition to lower/drop down. Yes, you can power down the car. Whatever you wish. My made my point. Be careful. Please.
