Default Fan loom for cosworth

anyone know where to buy new fan looms for cossies? cant find them on ebay anymore. need it bad :P heh.. If not, anyone know the colours of the 4 wires that goes in to the temp sensor on the rad. ?
I have a really bad loom in general, so the contact for the fan sensor isn't there :/

hmmm... okay. look at this one her... this is my fan switch:


is this a stand alone unit? or does it need signal from the ecu to work properly?
On one of the drawings "velocity" drew for a guy in here wondering about the same thing I cant see any ecu signals to the fan switch.

Temp sender for gauge is independent and has no effect on the fans at all it is screwed into exhaust side of head which is most likely guilty culprit can be confirmed by removing wire and earthing gauge should go to full indicating faulty sender.

That fan switch looks strange in that it has four pins it, you haven't changed to aftermarket management have you? Unless you have rewired it's more likely to be wiring than fan switch itself. Try bridging wires at fan switch if still no joy then will be power problem.
