Hi all,   My radiator fan switch seems to have packed up. I can bridge pins 1-2 and 1-3 in the plug and get the fans working. I've currently got the three pin blue plug switch at the moment but I've no idea if this is correct for my car. It's a 1992 non cat 1.9. Does the colour of the plug determine the temperature range of the switch? Would anyone know which is correct for my car? I've attached a picture of the different part numbers from ECP.  I've done a search on here but can't find an answer. Should I go for a Valeo one? Sorry for all the questions!
