After a catroshophic nightmare changing the glow plugs in my DTI i had to remove the head in fact i had to change the head but thats another story!!

Any how now ita all bach together i seem to have a plug left over and i cant for the life of me figure out where it goes!

Its a small 3 pin plug that is on the same part of the loom as the coolant temp sensor. I must go around that area somewhere because its clipped to the airbox and only has about 10 inchs if cable to move about.

It also has a purple rubber grommet around and it looks like it goes into a round hole!!

Any ideas would be great??
