what color vacuum line goes to the EGR and what color line goes to the intake manifold next to the fuel pressure regulator vacuum line?

Also, where do those color coded vacuum lines go to inside of the passenger side fender?

Thanks
 
From the intake to near the EVR, it's red (just before the EVR, it Tees and changes to green IIRC).
From the EVR to the EGR, it's green.

All lines connected to the intake itself should be black as I recall. It's only when they get near their intended destination or towards a control-device that they get color-coded.

EDIT: Here's a diagram that might help.

Good luck.
 
sorry im an r-tard :shrug: . what and where is the EVR? what and where is the vacuum source for the bundle of vac lines for the egr and air injection valves that go into the passenger fender well?

Thanks for all the help, I need to get smarter so i can start earning my keep around here :SNSign:
 
EVR is the EGR vacuum regulator. It controls how much vac goes to the EGR (thus how far the EGR opens. It's like how the gas pedal controls how fast you accelerate).

The EVR is under the passenger fender. You remove the liner and can see it and the AIR solenoids. They receive straight manifold vacuum. Here's a picture, courtesy of Keven:
