4wd Not engaging

I had a problem with broken vac lines to the front axle got those fixed but dont know where to connect them in the engine comparment. Its and 86 XJ with 2.8L V6. Any body know where to connect them?

Sorry, I dont know where to hook them up. However, you might want to look up a device called the Posi-Lock. This little unit bypasses the OEM vacuum system and gives you a positive front axle locking mechanism. I will be installing one of these babies when my OEM system gives up the ghost.
