Can anyone advise. I have been fitting mk2 16v clocks into my mk1. The only part I can't find the information on is the outside air temperature sensor wiring. The mk1 had two wires to the clocks to connect it(white/red and white/blue) but the 16v clocks only have one wire white red. I have connected white red to white red as the diagram on the net. Does the sensor just require a earth connection to make the circuit. Which sensor will I require? Thanks.
blue/white you just earth, factory ce1 its tapped into the female spade near fusebox which goes off in the engine loom and earths to the side of the head
