How do i hook up my Quadra Trac?

I just bought a 1977 Cj7 with Quadra Trac. There is vacuum line off my axles about 3" long with bolts in the end of lines. There is no interior so no switch. Can anyone tell me how this all hooks up? And is there a kit to replace the lines and switch. I know nothing about Quadra Trac.

There is no vacuum line on CJ axles. What you are seeing is probably just the vent line. There is an "emergency mode" for the qtrac that locks it together more like a traditional tcase. I believe this was vacuum actuated.

The switch is normally in the glove box. The shifter its probably for the low range unit.

That's about all I know about the qtrac. Try searching for a factory service manual (fsm) for a 76 -79 CJ. That would be the best source on how to hook up the switch
