4wd vacuum hose location question

I was just changed the starter on on 95 4runner w ADD auto and went to use my 4wd yesterday and it didnt work. I did some research on here and started looking at the vacuum hoses.

I quickly saw 2 vacuum hoses disconnected in my wheelwheel area with the color rings outround them. Up top on the fender everything is connected. I have searched on the truck and the board/manual and just cant come up with where these connect.

Does anyone know where the lines go or what general area/object I should be looking for? Or have a pic?

The part circled I see under my hood. But there are more vacuum hoses in the area near my starter that need to go somewhere.

Are the lines at your actuator connected? Might follow them back up to where lead.

I am going to do an in depth look this weekend. Pull off the wheel and skid plate to find where these lines are going. Thank you to everyone who has posted. Especially that vacuum diagram.

There is actually a vacuum reservior located forward of the wheel in the passenger side that has lines to it. The line enter the fender well near the ADD VSV valve and goes forward to the reservior from there. Diagram below is location of ADD system components.

Of course the lines ultimately end up at the ADD actuator to the side of the front diff. This may help:

You mean where they go at the ADD actuator or intake manifold or everywhere in between or all of the above?

I just reread your original post. I bet you answered your own question. You said you found them in the wheel well. The only ADD component in the wheel well is the ADD canister located fwd. See the pic I posted. This canister has two nipples for two vacuum hoses. PUt them on if it works backwards then just swap them to the other nipple.
