Rain/Light Sensor
Hi Guys

Anyone got a wiring diagram for the Rain/Light Sensor circuit?

I've had mice move in to my car and chew the wires. I suspect it's somewhere up behind the dashboard. The bloody stink and mess from those evil little bas*ards is unbelievable!

Anyway, thanks in advance for any clues.

It'd be also helpful if someone knows how to remove the sensor unit from the windscreen?

Red is the positive 12V and middle brown is the negative.
