vacuum line schematic

would anyone have a vacuum line schematic for a 99 150 4x4 5.4 motor?

i think i have a line that is not hooked up to anything.....i have a pink blue and a black that go to the shift actuater for the 4x4....the pink and blue are fine upto the solonoid...but i am not sure where the black one goes....

chipmunk ate thru several lines including the climate control vacuum line...but something does not seem right...a close up picture would be great or something telling me where the color coded lines go....i don't think that i have them right..

i had the 1 black hose going to a vacuum box by itself and that doesn't seem right..

have spent a lot of time searching and coming up with nothing that really helps

thanks

The black line that follows the blue & pink to the actuator is a vent for the axle and is just open to the air. You have others in question? General vacuum routing should be shown on the Vehicle Emission Control Information (VECI) Decal

the eci info only shows the emission vacuum lines...

i have the main vacuum line that runs to the first tee..1 line runs to the climate control the other goes straight thru to a check..thru that check does it go to the upper vacuum box? by itself..that just doesn't make sense to me..
i thought i could post a pic,but i guess not
i used to like chipmunks,but not after this...

thank you for your help...

at the bottom of the check it runs to the climate control ....the line in question is the one on the top left that runs thru the check...that goes to the vacuum box?or do i have the lines mixed up?

thanks

I need to pick up some info on vacuum lines as well, but I need it for a 98 F150, 4.2 litre V-6. Apparently a hole in a vacuum line somewhere keeps burning out idle control motors and keeps the "check engine light" on. I've looked and looked but cannot locate the culprit hose. If anyone can help, let me know.
