I noticed this nipple up around the throttle body. I don't see any hoses hanging out. Anybody know what goes here? The picture was taken from the driver's side. Hmmm. Maybe my transfer case vent hose can fit on there?

 

I have just looked at my Dakota with a 4.7 and it seams to have just a plug ( a cover on it ) not connected to anything. I would plug it hopefully some one else will chime in that has a 4.7 in a D.

 

it should have a hose on it, however i am not at home right now so i dont have the D here to check where that hose goes to on the other end for you

 

It looks like that nipple is part of the throttle body. Looking around at pictures of 4.7's it appears that some have a plug there and some have a hose. I wonder if it's for California emissions. I searched Hayne's and the service manual, and looked at about a million google images of throttle bodies and engines. Just can't tell where the other end of that hose is leading. I probably overlooked something obvious.

 

if you dont figure it out by thanksgiving bump this thread the wed before and ill check where it goes when i get home

 

Mine has a hose that connects to a round container thing under the fuse box/right behind the battery.

 

Hey, would it be possible for anyone to put up a picture of where that hose goes? All those little hoses on my D were all out of place. I have everything straightened out except that one. I figured out that when I put a plug on the end (brilliant!) the engine dies, as that nipple sucks in air. I'm thinking that leaving it how it is will end up putting a bunch of dirt and dust into the system. I can't seem to find any pictures or information pertaining to the hose. Can't find a hose anywhere or even the other nipple for that matter.

 

oops looks like I deleted the original picture. Here is is again.

 

that hose connects to something under my PDC i cant get a good picture of it

 

I'd look under the fuses right behind the battery, you should see a round thing with another hose on it, and most likely another open connection.
