I want to change the oil and I always fill the oil filter first but now hear the crank sensor should also be disconnected till the preassure builds up. Maybe i'm a little thick but I can't seem to find it even by the altenator. Can someone PLEASE show me a picture of the crank sensor on a STi 7 with a good description of it and what needs to be done?

 

Can't anyone help?

 

Its under the alternator, on the top of the cam belt casing.
