At the driver's side end of the front valve cover on the '97 3.0 wiring harness/motor, there are three plugs. They are ALL worked into that metal air duct network that is at least a part of the EGR system. One is green, one is brown and one is black. Each one has three separate vacuum fittings...one on one end and two on the other. What are they and how does one route the vacuum lines, given the fact that my EGR system has been removed on the 3.5 swap? It looks as if the "Boost Sensor" vacuum line routes in to the brown one. I'm getting a "MAP/Baro" code right now and I'd like to get it taken care of. Thanks guys.

 

i think they are actualy solenoids, this picture might be helpful....
