I have been using the R3 for a few months and it has saved me on multiple occasions. It’s connected via the 12V cigarette outlet and has been sitting on one of the included suction cups on my windshield, but I decided today I want to clean it up a little bit since the wires are messy. I ordered this kit from Radar Mount and was wondering if that’s all I need to do (as in tapping power from the rearview mirror). Because I did some brief research and seems like a lot of people are taking off the foot panel trim on the left driver side to hardwire their accessories, so my method of taking off the plastic trim behind the rearview mirror seems too good to be true that I’m scared it might mess up some electronics within the car. Does anyone have any experience with hardwiring accessories in Model 3 who can give me some guidance?
