I have a 22r 4wd, 4 runner and I am having problems like everyone, with the 4wd system staying engaged. I have manually unlocked, for now. I also disconnected the 2 vacume lines. So it can't engage. ATM. Can someone please tell me where the two lines go because the car has been stuffed around with and don't trust they are in the right location. As i would like to replace with new. And a diagram for the carby vacumes also would be great. Thanks. Tim
