Dana 30 front axle lock method working great!

We opted for something different that what we have read of the dana 30 axle lock. We used the origional vacuum diaphrams and the following...
Two 12 volt vacuum switches with a common, a normally open and a normaly closed connectors.
We wired the two switches to a fused 12 V toggle switch.
A vacuum supply from the intake to the vacuum resivor.
A supply line from the resivor to the two switches with a tee.
SW1 (engaged)  Vac. supply went to the normally closed port.
The common port went to the vacuum diaphram that engages the lock.
The normally open (switch off) is a vent.

SW2 (Engaged) Vac. supply to normally open port.
Common port to diaphram that disengages lock.
Normally closed to Vent.

Works Great!!
