Does anyone happen to know how a LX 100 vario works,
and what inputs it needs ?

After a happy hour on my back with flashlight and mirror
trying to decipher the plumbing, I think mine is connected
only to 12V and two separate capacity bottles. That
seems strange, but it works. Can anyone tell me how
? Alternatively, if I have misread the spaghetti,
please let me know about it.

Would it work better if it had a TE input ?
