I have a 4.7 out back il get a pic when i get a chance. lines that go to throttle body are brake booster and EVAP solenoid you also should have one running from rear of the manifold directly to the PCV valve on the Oil fil assy.

I also have a real thin line that runs to the dash by the looks of it i think 04 though is electric actuators for ac though im at a loss i do know valve cover is leaking so got new ones and exhaust manifold gaskets and hardware just never done them before
