Just a quick question, I was taking a look over my abf in my corrado today and looked round the back of the engine and noticed that there was a white plug just next to the drivers side with it not connected up, connector was lying next to it, it is just under the exhaust manifold, I followed the chunky wires back and they are all wrapped up and run along under the scuttle, get to the coil and do a u-turn and go all the way back and come and join up with what looks like into part of the loom.
Do you have any idea what this plug is or does?
