What is this?
Toward the rear of my 5.4, near the firewall, on top of the black engine cover near where the (I believe) PCV hose exits, there is a 1-2" long, silver, very thin nipple that looks like some sort of connector......Like something should be plugged into it. They're on both sides of the engine. Wha'tizzit?
