Re-wiring fan with switch & relay

[fastevo1]

It looks like that they guy who fitted a manual switch for the fan has removed the fan relay wiring which connects to the fan and temp sensor.

Is there a guide to re wire the temp sensor with a relay connected to the fan and a override switch?

Can't understand why fan had be connected like that, i fitted a fresh fan loom when it was restored.

Maybe use Haynes wiring diags, get it back to standard and then splice in a switch, though it wont really need one if the cooling system is in good condition. :agree:
