Thanks, that make sense. It is like the centre piece on a distrubutor cap. On the sensor it is one small area for the neutral and six bigger one for each gear. ( for the sixth gear I assume it is not used because it is a five speed gearbox.?) But is the ecu using the information for each gear or is that for later models? And is it possible that type of sensor is wrong. Some of sensors looks like the spring is on that side. I found a video on YouTube and on this I looks like the cap has the same distance like mine.
