2008 Dodge Ram spark plugs

Alright so my dad called me tonight asking me where his spark plugs are at on his 2008 dodge ram big horn which is pretty odd because I am normally asking him questions about my cars he has the 5.7 L he said he cant find the plug wires can someone help me out I have never seen his engine because I live on the other side of the country but if you can explain it to me maybe I can help him over the phone if you have a picture that would help because I cant seem to find one thanks
