I am One with the Force, and the Force is with me
I was asking about the camera power source as the newer Y's (and the rest of Tesla's range I believe) use Li-Ion low voltage batteries and the 12v "aux" line at the hitch is not currently functional (tested at the dealership before we picked up). All the other connections work (lights, brake controller, etc) so things are safe to drive, but if the camera doesn't pull directly from the RV's battery, then it would rely on that 12v connection to the car, and I'd be SOL on a review camera....I believe the electrical connection at the hitch is to trigger your trailer brake lights when your in-car brake controller activates them, and if you add a rear-facing camera to your trailer you need to wire it into the trailers electrical system.
Years ago I found some clamp-on extendable side mirrors on Amazon (sorry, do not recall the brand) that I keep in my X in case the rearview camera I added to my trailer fails, but so far it has not. However, for a variety of reasons I don’t recommend the camera I bought. See the bottom of this page to read what I think about it.
That being said, I'll look at the camera so I know what not to get.
I'll take a look at that product - hopefully there's some place where I can get them that isn't Amazon, as I have avoided ordering anything from/through them for close to the last 10 years...We’re using the Dometic DM-2899 Milenco Aero 3 on our Y and would fully recommend them! Once you have your method of installation dialed they are quick and easy to take off / put on and make the difference beteeen seeing or not seeing that truck coming up in the lane next to you…a must have IMO!
Here’s a link but will probably go to Amazon Canada but will show you the product
