Also, i know that the computer(or something) will lock it up (mine is an 83 1/2 ton) and when you press the brakes it will unlock.

What i'm wondering what the vacuum thing is for----which i partially understand will unlock it upon deceleration. Why is this nessesary(if it all)?

The reason why i'm asking is i will have to swap motors (long, sad story why--another topic) and the "new" motor has a different manifold with less/different/non-original vacuum line patterns.
