Does this stay powered with sentry mode on? I tried finding this wire on my 2023 MYP and couldn't seem to get a voltage reading on any of the Red wires using a clip type multimeter.Can verify that the red wire on the right side of the passenger footwell works as a switched 12v on the 2023 Model Y Performance. I wasn't sure if the trailer brake controller method on the driver's side would work on mine since I don't have the tow package, so I went with this method. In retrospect, I would have ordered the adapter and tried that first since it looked easier.
There are A LOT of red wires (not just 3). I counted 9 thin ones ranging from red to blood orange to slightly fuchsia, 1 thin red wrapped in thin blue, 1 thin red wrapped in thin white, 1 thick red wire (THIS is the one you want), 1 thick red wire wrapped in thick blue wire, 1 really thick red wire shown off to the left. The correct one was buried pretty deep in the bundle and took a decent amount of tape-cutting to access.
I thought finding the correct wire would have been the toughest part, but I had trouble tapping into the wire with the t-tap connector that came with the Uniden radar detector wire kit I had ordered (link). The blue connector it came with would have been fine for the thinner wires in the bundle, but probably needed a slightly larger awg wiretapper for the middle-size wire I tapped into.
The last part I would have liked to avoid was grounding the other wire. There weren't any bolts on the frame within reach so I had to drill a new hole. Went through two drill bits that weren't sharp enough, and a self-tapping sheet metal screw failed to penetrate as well. Finally got it drilled, but a bad ground connection here made me waste a lot of time because I thought the hot wire was the issue.
Got it working at the end though. Thanks to everyone else who'd already tried it and posted their pictures.

Make sure someone is sitting in the drivers seat with pedal on brake. It turns off quickly after you stop and get out of the car or no one is in the drivers seat.
The one I thought was it was the right one. I just never could get a reading without actually tapping the wire but thanks for the heads up as it turns off WAY faster than I was expecting.
Note, this will only work of you have factory tow package ticked....otherwise it's software blocked and no power to the socket.

. Besides, I usually have Waze up on my Hansshow F68 display, so I know about the police miles ahead of time anyway. I also like that it is easier to reach the mute button on the radar as well.
