Had an accident with the ECU I am using in a Bay conversion.I put 12volts to the ECU trigger wire to the cooling fan relay - it earths inside the ECU.Guessing I have shorted something out-because the fans do not come on.Have some pics of the unit.It came from an early 90's car.I have just pulled an ECU from a 93 car,but it has only 3 plugs whereas this one has 4.So if anybody has one surplus to needs,willing to buy it.

Think I maybe able to help
I have a spare from a 91 EJ 22
Currently overseas till the 19th
Let me know If still needed and I will check when home

Thanks Gaz - I have contacted Andrew at AGT to enquire, if I fit a Davies Craig stand alone fan controller,will it have any effect on the ECU operation if it's not working the fans.He assures me there will be no problems.So have ordered the controller.If it turns to shit,I will be in touch.
