06+ have a center diff with a permanent mechanical engagement so even when power is fully dumped to the DCCD to the system isn’t completely unlocked, hence no fuse.

up to '04, the DCCD could be 100% unlocked by pulling power to the DCCD(that fuse activates a relay which open the DCCD main wiring, thus open circuit). Main reason why putting a six speed into a non DCCD car results in FWD unless you install an aftermarket DCCD controller, or send a 12volt 10amp load to the DCCD.

Ok, I understand the why. But now I would like to know how that works mechanically. If the entire AWD system is connected mechanically, how does a simple circuit allow you to stop sending power to the rear wheels?
