R107: Can someone look under their hood real quick?

[350SL4spd]

Hi,
I just put my new motor in my 380SL and have three question marks as to where things hook up: (They weren't hooked to anything when I bought the car...)

1) There is a large grey vac line that rund down the top of the firewall from behind the brake booster. What does it attach to?

2) There is a Bosch fuel control unit (of some kind) just to the right of the ICV, above the thermostat. It has two fuel lines on top and a red vac line at the bottom. On the top there is a what looks like a "U" shaped vac connector. Does yours have a vac line and where does it go?

3)Where does the electric for the smog pump hook up? I have two wires (to a two-prong plug) out the right side of the smog pump, but can't find where they hook into the harness?

Thanks alot!! I'll post pics of her when I get a chance!
