I took delivery on a 2023 Model X in early December 2023 with the trailer package installed. The unit came with a seven way wiring connector. I have not installed a brake controller but the wiring for a four wire setup should work with a 7 to 4 wire converter. With the converter installed, I am getting a 3 Volt positive measurement on the brake, left, and right turn signals, along with a good ground. The three volts stay on constantly while the car is on, and does not respond to input from the brakes or turn signals. I stumped the local Tesla Ranger, and await some other solution from Tesla. Anybody run into this or better yet have a solution?
