Where do you find the EGR on a 1990 Acura Integra?

== == == == == == == == I have a 1991 and the Haynes manual only shows the removal/installation of the EGR valve on the Legend models. What I find odd though is that there is an EGR part for the 90 - 93 Integra and it's not cheap. The only thing that the manual says is that you should refer to your VECI label located under the hood to see if your vehicle has an EGR valve. All other illustrations are shown from a Legend.
