    There are three. I know one is EGR, but which one and what are the other two?

    TIA!

    Mine does not have the grey one (A/C).

    I am guessing the other three are:
    One is for the secondary air (pair valve)
    One is for the fuel pressure egulator
    One is for the egr and egr modulator

    just curious of what color is which.

    my 94 only has three, does not have the egr one, it's done by a temp. switch on the intake, the gray one is for the AC idle up, the brown one is for the pair valve and the blue/green one is for the fuel pres. reg., just did the delete of the pair and egr, the only one I kept was the fuel pres. reg. and you can do away with that one and just use one vacuum source to reg., but I decided to keep it............
