Reference the reverse selector switch ( for reversing light) mentioned earlier in thread, I am pretty sure that this is what it is, but I cannot see it listed in the Parts manual. My car seems to have a lashed up system (see photo) probably because the sensor failed at some point in its history. I have removed the sensor and it has a small probe which appears to have lost it 'spring', so no longer protrudes as necessary. Any body have a clue if the sensor is available or repairable?
