as above, on the KR engine. On the ECU theres two plugs. In the top left plug theres a black wire that runs down the rain tray/ scuttle panel, then pops out through the wiring for the coil. Its quite long and relatively thin, it enters the bay near to the coil.
Where does it go? Mines just hanging loose and since i guess its an earth for the ECU i think it may well be the reason im getting no spark from the king lead and hence not firing.
Thanks.
