Well I've been wanting to install a toggle switch to engage and disengage my CAD for a while now and finally took the time today to tackle the project. It will allow me to use the low range on my transfer case and remain in 2wd. It's very handy when moving trailers around in tight spaces like steep driveways and such in the mountains where I'm primarily working. I used a Clifford MJTV-5 pneumatic toggle switch and 1/4" air brake line. @TFaoro this should work for you as well so you can eng/disengage your CAD. 

This is awesome! I had been contemplating a posi-lok but really I only need to for backing our 5th wheel. Reverse is geared way too high in 2wd high. Need 2wd low so this is the perfect fix! Thanks for posting. I never even thought about doing this

 

Write up?

That is pretty cool!

I need to do this this too, looking forward to a write up 

Here we go now all these switches will be sold out for a while. ..
