Where does the main earth to the engine block fit on the engine?

It was fitted but left off when the clutch was replaced recently!

I can't see where it would have gone.
I have a Knocklink fitted, and think the earth went some where around there?

Thanks

 

Have a look at this pic mate. I took it when I was doing my knocklink install. I think you can see the engine earth at the right of the pic.
