It's the 1996 Dodge Ram in my signature.
I love being able to run the transfer case 2WD in lo range, but despise having to get out, pop the hood, and swap vacuum lines all over the place to get my CAD to engage/disengage, so I started looking around for a better solution.
I looked at PosiLok, and while that was great, I want to be able to control the CAD unit with a switch, not a lever or cable. Essentially, I came down to two ways: 1) Use 2 vacuum solenoids on the vacuum lines and reuse the stock CAD unit or 2) Put a spring on the inside of the CAD unit to hold it in disengage position, then use a 12VDC solenoid to engage it.
What are your thoughts?
