It is similar. You go the other way around the waterpump and only to the P/S pump. Don't let some stupid moron tell you this will make the waterpump turn the opposite way, as long as the back of the belt is on the w/p it will spin the same way.
Not to be an ass, but do a search. I say this because I had the same question last night, did a search and found not only the route but also a diagram of it and proper size.
There are at least two threads up with that post included.
Good luck - I am going to just buy the UPR bracket with pulley as I don't want to play all kinds of belt sizing games when I upgrade to a supercharger.
