Default 4x4 vacuum

I changed the front brake lines on my 2005 blazer that is just used on property as a plow truck. I am not sure on what I have done but now have no front wheel drive . It is equipped with the 3 button system. When I put it in 4 high the light stays on and the actuator moves the cable maybe 1/4" . Looking at the vacuum hoses closest to the ABS module, I noticed the hoses in the picture....does this connect to a fitting that I cannot find....thanks

Yes, the fitting is on the vacuum reserve tank located inside the fender. Stand on your head to see it!

I have looked all over for a nipple to attach the hose too but no luck

Another good post from that thread:

This image show the orientation of the reservoir, (the arrow points to the front of the vehicle):


Here is another view, (the arrow points to the front of the vehicle):
