Hi everyone can anyone help I need a wiring diagram and colours for the two wires that connect to the termostate on the small aux radiator in the front wheel arch. I have wis but cannot find anything relating to the thermostate connector wires, I know one is a chassi ground brown wire, just not sure about the other? Cheers love these cars.
