I installed Power trunk on my Model 3. It is very cool product and works very well. I can highly recommend Tesplus power trunk. And this installation Tutorial video very helpful. https://youtu.be/i5GRQxT2HsA
I did not see a SD Card in my kit, what is on that and where do we get it.
Also, would be nice to see a video on installing the kick sensors.
SD card will not be included in the package. An SD card is only required if the software needs to be updated for any reason. Below the message is a link to the Kick Sensor installation video
