I hope someone can help … I just finished putting the engine back in having fitted the brilliant “Bleazey” Centra upgrade.

After checking everything is connected I have spotted that the knock sensor (which is a circular disk bolted to the right hand cylinder head) ends in a small oval connector which places near the coil pack. I unbolted the knock sensor - I didn’t unplug it. However I can’t find any corresponding connector in the front wiring loom - everything is connected - except the knock sensor. Could anyone confirm if this is either left floating or where in the loom it plugs in. Occasionally we get a nut left over but I’ve never had a cable floating!

Any help greatly appreciated.
