Ok i followed the diagram but i still have problems... Having the "correct setup" the axle stays locked all the time and the 4x4 light stays off. But when i switch the yellow and green lines on the CAD the axle stays unlocked all the time and the 4x4 light stays on.
It seems i have a constant vacuum from the yellow line all the time and none from the green line. It seems i need some help figuring out what is wrong.
Also on the diagram there is black and white figure on the yellow line that goes between the CAD and the T to the black line and indicator switch. What is this?
