Finally got the vacuum lines hooked up on my truck. My truck has a switch that is mounted in the dash. I have one line going from the intake to the switch, then there is two lines going out of the switch, both of these lines I plumbed straight to the 2 nipples on the rear end. When I flip the switch one way, I have some vacuum on one line at the rear end, when I flip it the other way I have nothing in either line at the rear end. I plumbed the whole system with 3/8 hose. I took the truck for a test drive and it will not shift. I dont know much about these systems so if anyone can tell me what I did wrong or what I can try to get it to work it would be much appreciated.
