T100 ADD 4wd problems

I have a 95 t100 and just noticed that 4wd will not engage(worked fine last sping). I located the vacuum lines on the acuator and firewall and they same to be intact with no cracks.

Here is the strange thing, while trouble shooting I reversed the lines on the acuator and then 4wd engaged as soon as I shifted into 4wd?

My first thought was a bad line so I switched them back to std on the actuator and reversed them at the electric switches, same thing instant on?


anyone have diagram for the system?
