Digital LDA: How it Works & Setup Guide

The construction/installation shouldn't be a problem for me.

But I have a T4 2.5 TDI with 75 kW.
It doesn't have a 4-pin connector, and therefore doesn't provide 5V.
The LD sensor has only 2 connections.
I have no idea what voltage the sensor here is operating at.
Can the digital LDA also display the suction range?
How does she react to rapid changes or spikes?

Best regards, Klaus.
