Hello. First time post here. I am trying to install a radar detector in a 2018 Model 3 performance. Sounds easy enough, but it seems that I cant find any pictures or videos that match my car. I'm not used to working on a car that I don't have manuals and a schematic for, not to mention nearly impossible to find components. All I want is some place to get 12vdc, switched or unswitched, doesnt matter. I have no problem manually turning it on or off. I have the detector installed and wires run down the A pillar... some help as to where to connect from here would be appreciated. Thanks in advance!
