Do you have the parts yet? It's pretty straight forward once you have the parts in front of you.
The oil line connects with a banjo bolt from the engine (beneath the oil filter) to the top of the turbo. The original banjo bolt will fit on the engine side but you'll need the correct banjo bolt for the turbo side.
The water lines screw on to the back of the turbo and connect to the engine using jubilee clips. You may have to trim these lines down as they're often supplied with extra length.
