If it's deep Inside the wing and has a black tube coming out of it, that will be a vacume reservoir

well that also makes reasonable sense as the little black tube buggers off inside the cab along with the heater hoses

Willo,

Read this for a description of what a vacuum box does...

http://www.enginebasics.com/Engine%20Basics%20Root%20Folder/Vacuum%20Basics.html

Mine has been moved several times, the original black hard pipe was cut and a piece of rubber pipe inserted.

As other have said, in a TJ vacuum is used to control heater vents.  As I've removed the heater, I was originally going to do a away with the vacuum box however probably going to keep it as TH350 autobox is vacuum controlled.
