HELP!HELP!HELP! SERPENTINE DRIVE BELT.

I HAVE TO FIT A NEW SERPENTINE DRIVE BELT TO A 1991 VOLVO 480ES 3 DOOR HATCHBACK AUTO. THIS CAR HAS SEVEN PULLIES THAT THE BELT HAS TO GO ROUND...IT HAS FIVE GROOVED"RIBBED" PULLIES AND TWO SMOOTH PULLIES... ONE PULLY IS THE WATER PUMP(SMOOTH), THE NEXT ONE IS THE CRANK PULLEY(GROOVED),THEN THE POWERED STEERING PULLY(GROOVED),AIR CON(GROOVED),ALTERNATOR(GROOVED)AND ONE SMALL ONE ABOVE THE CRANK WHICH IS ALSO GROOVED BUT I THINK THIS IS JUST A GUIDE WHEEL. THERE IS ALSO A SMALL GUIDE WHEEL ABOVE THE ALTERNATOR WHICH IS A SMOOTH GUIDE WHEEL..THAT MAKES SEVEN PULLIES IN ALL.WHAT I DESPERATELY NEED IS A DIAGRAM FOR THE ROUTE THE BELT MUST TRAVEL AROUND THESE PULLIES PLEASE.I HAVE CONSULTED A WORKSHOP MANUAL BUT THIS ONLY SHOWS THE ROUTE FOR A FIVE PULLY ENGINE(NO AIR CON)...PLEASE HELP :(
