Ok this diagrams for you.I'm at work right now,if you need more info,let me know il'll snap some pictures.
One thing when you will be installing new plugs ,get yourself rubber hose that fits on the top of the plug( i got one from Autozone $1,ask for a rubber hose,about 10".)
It is for "threading" the plug,this way you will go gentle and wont ruin the thread in the head,i also use gray anti seez paste .
And one more, watch that torque!!!
