At the risk of providing more useless info - on my 97 the IAC and EGR vac solenoid plugs are almost identical. The IAC has a black wire with a bright yellow stripe, the EGR solenoid (little solenoid "attachment" thing that bolts to back of upper intake by the IAC) has a black wire with what looks like a pale tan or white (very dirty back there - but it's a pale light color) stripe on it. (Yes there are two wires for each plug but the lighter ones were too dirty to say what color the wires were for sure) The bright yellow stripe stood right out though.
