I just hid the sensor near module itself because I wanted lights to always turn on. You can mount it in the corner of windshield and the A-pillar in order to work with the sunlight. Bluetooth allows you to configure the device. You can set CH/LH lights, set time after which the sensor will turn on and off the lights and light sensivity. I did bought used OEM switch with proper cover just to use cover. The one which came with the switch I orderd from china was for VW cars (different cover) I didn't found the one for
Ibiza. As for the red trim it's called el-wire, I have mounted it also around door trims and central console the one with passenger airbag.
