Earlier this year I installed a Thinkware F750 dashcam in my S85D. After the install every firmware update comes with a failure message. Recently took my car in for service and they told me the installer unplugged the rain sensor to power the camera. I had followed the advice given in several places on the forum and used the plug above the microphone grill in the headliner. The picture at https://teslamotorsclub.com/tmc/attachments/img_2016-jpg.99065/ sums up all of the electrical connections I used. Thanks to liuping, wk057, and the others for the invaluable information about installing a dash cam. I wonder if something came unplugged while I was installing my dash cam, does anybody know where the connector is at for the rain sensor and how hard would it be to check to see if it is still firmly seated? Thanks.
