part identity help?
 

long time lurker,first time poster.

i just aquired a 95 3500 5sp truck and i am going thru all the normal post purchase check stuff.

on the the drivers side inner fender is a vacuum valve with the hose attached and 3 wires coming out of it. some one had cut the wires. i reconnected them but i cant find in my crapp haynes (yah,i know) manual what it does.

thanks for any help!

this board is a excellent resource.

where does the vaccume lines go?

i have not tried the cruise but i will on my way home tonight.

the vacum line T's into the brake booster line and what looks like the HVAC control lines under the hood.

i will shoot a picture and post in a few minutes.

i think that its the cruz controls but not sure either

My guess would be cruise control or a low vacuum warning switch. I know the '90's model Fords had low vacuum warning switches that looked very similar to that...although every one I've ever owned never warned me of low vacuum :nope:

confirmed cruise control works.
