Head and intake vacum
On my car there were 3 ground wires attached to the drivers side head. There's a small metal bracket attached the back of the pass. head that holds part of the wiring harness. On the back of the intake manifold there is a large vaccum hose that goes to the brake booster. There is a small vaccume hose that goes to the HVAC, and there is a sensor (map sensor). Now the pcv is set up to where there is a hose going from driver's valve cover over to passenger side valve cover (connect with a y connection in the middle) and the other part of the y splits off and run under the fuel rail on the passenger side to the front of the intake manifold.
1. is the knock sensor (shouldn't have to mess with this)
2. is the oil pressure sending unit (same as above, but the hose right in front is the brake booster hose.
3. is the cam position sensor (shouldn't have to mess with this)
4. HVAC vaccum
5. Map sensor plug in
You can see on this particular car the bracket is on the drivers side head. The three ground wires really can go anywhere as long as they are tight. It's not like they have to be at a cetain spot on the head. Just wherever works best on the head.
At the very top of the picture you can see the pcv stuff I mentioned and the y connection.
