vacuum Lines

Hey guys need some help. I have to redo my vacuum lines because when I got  the engine swap done some vacuum lines was cut and not fixed. what I need is a pic of the air pump and the hoses that go to it. It still has the factory intake manifold on it with the cfi still on it and connected to the computer. This is a biggie but any info helps. By the way most pics of engines in repair manuals suck.

I don't have a CFI 5.0 to take pictures of but maybe this info from the 84 shop manuals will help.
The output from the air pump goes through the bypass valve. Then it goes through the diverter valve. From there it goes either to the exhaust manfold or the catalytic converter.
There are two solenoids that control the valves. The two valves plus the MAP sensor are mounted as a group in the area of the right shock tower. Both solenoids have a red wire (12 volts). The bypass has a white/red dot wire and the diverter has a green/black dot wire.
There should be a vacuum hose from the solenoids to their respective valves.

@softtouch.  What books did you get this out of? I have a 84 'bird with the 5.0 and this is the best diagram I've seen. Thanks!

I bought the Ford shop manuals from Helm in 84 when I bought  the 84 3.8 TBird.
