Hi I have recently removed my wiring loom to incorporate the trip computer and cruise control wires, after adding these wires into my loom and reinstalling the loom, the trip computer works, not sure about the cruise control yet as the car is not registered, however I am having trouble with the interior heater fan, there is no earth going to the fan relay if I short the center wire (brown and white) of the LP check relay under the bonnet it works fine can anyone advise me where this wire is supposed to be earthed.

Thanks

Jamie.
