So maybe a stupid question here..?

How can the center diff electronic controller controll the lock or power distribution of the center diff without any "physical" electronic connections to the differential?

 

Its hydraulic

 

Hydraulic lines.

 

with magic

 

I thought it was witchcraft?

Good question though man, I didnt know this. Thanks for asking.

 

The SDC is used to adjust torque split between front and rear differentials by controlling the current to the centre differential solenoid. The centre diff is essentially a limited slip differential with adjustable preload, where the preload is propotional to current. This current can provide 0% to 100% lock of the centre diff. When at 0% lock, the centre diff operates as an "open" diff with a mechanical torque distribution of 65% rear, 35% front (60:40 in some vehicles). As lock is increased, the preload increased, requiring more torque difference between front and rear before the centre differential will slip.

 

Wow... just wow.

You sound so sure of yourself for someone so wrong.

 

Wish I had SDC in my car, I just have ACD Super Differential Control would be mucho bettero.
