Hi I'm having trouble working out where a particular part of wiring goes for the radiator fan switch. I have a 205 xe 1991 tu9 engine, and there are 2 wires going to the radiator switch and then 2 of the same coloured wires coming off it again back to a brown connector, but there doesn't seem to be anywhere to connect the brown connector.Does anybody know where this should fit to as someone else has fiddled with the wiring before I got the car. Tia
