Front axle vacuum disconnect interrupt idea, will it work?

My front axle disconnect is still the stock vacuum disconnect setup. I was thinking, what if I took one of my old vacuum switches (from the pulse air system control on the valve cover) and put it in line with the vacuum pulled off the manifold for the 4wd system. This way, I could turn off (close) the switch and not allow vacuum to reach the transfer case. Then if I were to shift into 4 low, it would really be 2 low since the front axle shift fork will not move. Think this would work? And can the vacuum switch take 12 volts? or will I need to find a place that has lower voltage to pull from?

Sounds good, but I'm wonderin' why you wouldn't wanna pony up for a PosiLock and not only have something which will do just that, but will also eliminate a source of problems...sure, I realize that it's expensive, but it's also a dependable, well built piece...

I just replaced everything on my disconnect system last year, it's all new and working great. So why replace that all again so soon? And I already have the switch, so it's not like I'm spending any money, just some of my time.

i agree with goatboy the posilock is a great piece of gear. i just recently installed one and a cast shift fork, took just over an hour. its quick easy and painless, plus you can run 2Low if you needed to.

You are missing the point, I asked if this could be done, not if there is a better option. I'll just do it and if worse comes to worse I'll fry a vacuum switch in the process.
