95-96 Cam Plug & oil cooler ?

[dsmdion]

I have a 95 TSI AWD and I need to know what the plug is called that goes into the hole where the CAS would normaly be on the other DSMs. Also where is that long line on the oil cooler suppose to go. Mine looks like it screws into the cooler, but it looks like its plugged of on both ends of it, so I don't know what the hell it would even do if thats the case. I have the two normal hoses that go there, but then that thing was on there as well.

Thanks.
