OT ETKA Request - 95 Jetta 2.0 engine

[ggehrke at gmail.com (GGehrke)]

Looking for diagrams of the 2.0 engine for a 95 jetta.  Roomate's car
is hemorrhaging oil and water on the carport floor.

Specifically need what I think is the oil pressure switch on the front
of the engine (plug into the top of the oil filter receiver thingy)
and what I think is a coolant return fitting of some sort on right
drivers side of the engine - it's a manifold of some sort that plugs
up to the head and has a couple inlets, outlets, switches, etc...

Part numbers on either of those would be awesome too if my
descriptions of the parts are sufficient.  I don't have ETKA on my
laptop (Apple MBP - I don't suppose there's a mac ETKA...) so I can't
look it up myself.

Thanks!
