it sounds it me like its wired to a switched live and not the water temp sensor which is what i think would activate the fan when the water comes to temperture or else its the termistat im not sure thats just what i think it might be hope its something small to fix and not wiring

There's a pressure switch that sits in the aircon piping behind the passenger side headlamp. If this isn't connected then your cooling fan will run soon as the ignition is switched on. It is commonly caused by the removal of the aircon system. You can bridge the connector to get the fan to operate as normal if the aircon switch has been lost/binned.

Look in this area of the bay:

You will find the aircon pressure switch connector:

(This is a mk2/3 version, the mk1's should only have two pins from what I remember)

Now bridge the pins like so:

I'll let you decide how neatly you do it but make sure to tape it up securely with insultating tape to avoid water ingress.

Hope that helps buddy,

Yeah, you can doublecheck by warming it up with a roadtest and letting her sit for ten minutes/till fan comes on.
