Connected to the MAP sensor? The EVAP should be at the front of the engine.
The small port on the MAP sensor is for the HVAC. That controls the vents in the car for defrost and heater and A/C. If the vehical you are putting this in has vacuum controlled vents then tou can hook it up there.
After another look at that pic that hose looks like part of the PCV hose that runs to each valve cover. The complete hose will run from the driver side valvecover around the back of the intake, then split and hook into the passenger side valvecover in the rear and continue forward to the front passenger side of the intake just behind the throttle body. The PCV valve is located inline where this hose hooks up. I will post some pics tonight if you need me to.
