The underpressure is taken from the underpressure system of the engine. Its a T-pipe that also connects to the brake booster. From there it goes to a small reservoir for better pressure and then to two valves. So in the end it is underpressure to the left of the membran (pushing the rod into the differential) or underpressure to the right of the membran (pulling the rod out of the differential), which activates or deacrivates the locker. Hope that can be understood.

Here is the system, reservoir and valves. The valves are disconnected, as I need to modify the switch inside the car. It just has 2 positions and no zero, so whenever I start the engine the membran is pulled away from the differential. Didn't move since 10.000km as the locker was open and not assembled with some rougher roads so I guess the zero position is safe for driving.

Forgot an important image.. Here you can see the rod I was talking about.

Inside of the diff should look something like this, but I never opened it myself.

It looks exactly like this:

With grandpa's welding skills, aka No one is going to see this....
Anyway, it works somehow I am putting some quicksteel around the weld from the outside, hoping it will seal whatever causes the "sweating".
