Ill take a look at mine..
Ok one red vac line and black vac line run to firewall area. I assume they control AC /heat They go into the passenger side corner of intake plenum. Just to the right of that, a vac line runs from plenum to some where around the coil area. That connection just may be hidden under the plenum some where.
I looked with my cowl on so if your is off it may be easier to see.If not just feel right below where upper and lower intake come together...on the passenger side.. Hope this helps... NOTE!! Mine is a 2001 but should be close to the same...
