its pretty easy man..
Mount a can, then bung up the intake where the breathers enter it.. Route the pipes your have removed from intake to the catch can.
Have a play to figure out what bits you need in terms of piping (size, length) etc.., then go for it.
There is a breather on each rocker cover (on the top) and one at the back (top of) the crank case which is pretty close to your turbo compressor wheel.
most catch cans only have to inlets, so figure out which two you are going to route to the can..
Im planning to route two the two rocker cover breathers together then into one inlet, and the crank case breather into the other can inlet.
(wheather it is safe to route the two rocker covers together im not sure, but i dont see it being an issue)
