Hi,
Does anyone know the pinouts on a sierra cosworth ignition module.
Im actually stuck with the 2 wires that go to the ecu(pin 24+25). I know 1 must be a trigger wire but i cant figure out what the second one is for?

Anyone have any ideas? Im putting a motec ecu into my 4x4 saph and hopefully this is the last complication before its running again

Thanks
John
