They look like the smog vacuum lines.

They are for the Air Injection(AIR) system, they go from the solenoids in the passenger fender to the componets of the Air Pump system.

So since I dont have a smog pump im thinking I can just plug them and not use them. Is this correct.

two are for the smog pump, one is for the egr, and the other gos to the upper intake manifold. If you still run the egr you will need one of those, and im not sure of the purpose for the one to the intake manifold.

Red is supply for EGR. Goes to a part in the fender.
Green is dithering line from part in fender to the EGR valve.
You need both to run EGR valve.

Orange is AIR bypass supply line. First part after the smog air pump.
