Looking for a vacuum diagram for b5 1.8t
I'm trying to locate a good vacuum diagram for a 98.5 1.8t, preferably complete with labels. I've searched and come up with these two pictures labeled with numbers, but I need part descriptions as well. If anybody can help, I'd appreciate it.

RE: Looking for a vacuum diagram for b5 1.8t
This is for the second attachment:
1 - To EVAP canister
2 - Evaporative Emission (EVAP) canister purge regulator valve -N80-
3 - Check-valve for EVAP canister
between EVAP canister and intake manifold before turbocharger
Installation position (light/dark side): Arrow points in direction of flow, as shown in figure.
4 - Air cleaner housing
with Mass Air Flow (MAF) sensor -G70-
5 - Turbocharger
6 - Combination valve for secondary air injection (AIR)
--------------------------------------------------------------------------------
24-178
7 - Fuel pressure regulator
8 - To brake booster
9 - Check-valve
Between brake booster and intake manifold
Installation position (light/dark side): Arrow points in direction of flow, as shown in figure.
10 - Vacuum booster
11 - Check-valve
Between brake booster and intake manifold
Installation position (light/dark side): Arrow points in direction of flow, as shown in figure.
--------------------------------------------------------------------------------
24-179
12 - Vacuum reservoir
Installation location: Under wheel housing liner in front left wheel housing
13 - Secondary Air Injection (AIR) solenoid valve -N112-
Installation location: Below intake manifold
14 - Crankcase ventilation
15 - Check valve
between EVAP canister and intake manifold
between Leak Detection Pump (LDP) and intake manifold
Installation position (light/dark side): Arrow points in direction of flow, as shown in figure.
16 - to Leak Detection Pump (LDP) -V144-
--------------------------------------------------------------------------------
24-180
17 - Charge air cooler
with charge air pressure sensor -G31-
18 - Throttle valve control module -J338-
19 - Recirculating valve for turbocharger-N249-
Installation location: Below intake manifold
20 - Intake manifold
with Intake Air Temperature (IAT) sensor -G42-
21 - Vacuum diaphragm for boost pressure regulation
When the combination valve is opened, the mechanical boost pressure regulation valve in the turbocharger is opened and secondary air is thereby channeled past the turbocharger directly to the catalytic converter
--------------------------------------------------------------------------------
24-181
22 - Wastegate bypass regulator valve -N75-
23 - Mechanical recirculation valve
24 - Pressure control valve for crankshaft housing ventilation
25 - Secondary Air Injection (AIR) pump motor-V101-
1 - To EVAP canister

First picture.
1. Hose from airbox to turbo.
2. Arrow showing air coming in from maf?
3,4,5,15. More arrows showing flow.
6. Pcv valve
7. Recirculation hose for diverter valve.
8. Another arrow.
9. Pressure hose from intercooler to intake manifold.
10. Bolt.
11. Manifold air pressure sensor(boost pressure snesor).
12. Intercooler.
13. Duct to guide air to intercooler from front bumper.
14. Pressure hose from crossover tube to intercooler.
16. Crossover tube.
17. Pressure hose form turbo to croosover tube.
18. Vacuum line for diverter valve.
19. Diverter valve.
20. Pipe.
