Answers :

Firstly take the old one out by cutting the wires aboput 2/3 inches above the sensor then unscre the old sensor with a 22mm spanner then buy a universal sensor from auto factors a three wire is twice the price of a 4 wire sensor and the box of the 4 wire one is a colout coded wiring chart as the colours do not always match up so use the chart to sort then out ,the heater wires can be connected either way around though ,then refit the new sensor and use a block connector to reconnect the cables following the cable chart ,easy shouldnt take more that 20 mins to do .
