i have two hooked up right now and theres a third that goes under the intake but its capped offat the end of the hose------MY MAIN QUESTIONS IS: WHY IS MY CAR MISSING???? MAYBE o2 sensors??????????
Hmm...not sure on the Systemax...but there is a hose (if your looking at the front of the engine) that comes from the bottom left of the front of the intake that goes to the charcoal canister...
In the back of the intake there is a "tree" that screws into the back of the intake and the red hose goes to the fuel regulater, the black goes to the EGR I believe (on passenger side), and the thick short hose goes to the "S" on the firewall vacuum tree on driverside firewall...
The pcv valve runs from the back of the lower intake to around to the front right of your intake...
The back left of your intake should be plugged...
Hope that helps a little bit...Pics help out a lot you know
