In the above link is a photo of the vacuum motor. On the black piece is a vacuum nipple in the small "hump" and that is where vacuum is applied to disengage the axle collar. The nipple on the metal part of the large round housing for the diaphragm is the engage port. The nipple on the shaft housing is for the 4x4 light.
Hope that helps.

Well when i lifted mine they got broke i know the metal lines attatched to the frame there sitting on top like a top line ,,middle ,,low ,,i need to know what top hooks to on axle,,what middle hooks to,,and what the lowest one hooks to.. thats the only way i can figure to reference them..

Why don't you just go to the junkers and grab a vac harness off an old one. I got the whole vac line harness (both sides) for $8. Plug n play.

ParadiseXJ is right, that would be the simplest and quickest route.
You can figure it out with a vacuum gauge. You need a vacuum supply to the tc switch, an "engage" line and "disengage" line to the vacuum motor, and you can just plug off the 4x4 light port unless you honestly can't tell when the 4x4 is engaged.

Well i cant go that route because i lifted it to high the stocks wont reach i hooked them up last night before Got your message Joe Peters and read your message and went to test today and man the luck for once i must have got them all right because i have the 4wd light and all when i put in 4x4 i had to get it out in our massive snow and ice storm here in oklahoma even if i still need to alighn the front end..Thanks for the guidance.
