to op. if you run the line behind the hole that you are going to plug, then you'll have to get a water line for it. it's basically water line in and out. if you pluged that hole i suggest you plug the hole behind it too.

the down and upper hole is for oil cool and both the back and front are for water coolant. the front hole goes down under and back of the turbo to the coolant pipe. the coolant pipe is big and silver about the size of a half dollar size in diameter running to the water pump in front of the block. you cant miss it. the coolant pipe should have a tube stick out for that line to front of turbo. connect the hole in front of turbo to that tube stick.

correct me if i'm wrong.

if i were you, i'd run the watercool lines. that's how they were invented anyways.

hope this helps
