I was told you needed some sort of control module or something when I looked into it. While everyone told me it was completely mechanical- it is computer controlled.

You need the transfer case and front diff from a Escalade, Denali, or Silverado SS. The Autotrac version won't work because it requires input from speed sensors to engage the front clutches and the front diff is a part time design.
My NP8 transfer case doesn't have any electronic interface, it is strictly mechanical. Not sure how it works, maybe torque sensing clutches?

The front differential is different between the AWD and 4wd trucks, the AWD has a one piece axel, without the engagement solenoid. The transfercase in the C3's, SS's and early model Escalades and Yukon Denali's are NVG 149's, which are mechanical with a viscous coupling. The later model Escalades and Yukon Denali's use a Borg Warner transfer case that works as a center differential in conjunction with the traction control "which may be why you were told you would need contoller to make work". The NVG 149 would surely be the one to use.

Do the NVG 149 cases have any electrical control?
