I can't find where to put the crank lock pin. I have a 2003 A6 2.7.
The only thing I can see has a sensor wire coming out of it.
I thought it was supposed to be a plug with a bolt beside it to hold it in.

Anyway, can someone direct me to the HOLE...?

 

You remove the crank sensor and put it in there. Personally i never use it, i put on the cam lock bar then use some white out and mark the crank teeth in relation to the block. Much easier and works just as good.
