Tachograf SE5000 – schemat podłączenia, lokalizacja sygnału „imp”, opis złącz

Hello, I need wiring diagram of this device. I need to find where is "imp" signal. The printed diagram on top of device is broken. There is 4 connectors white, yellow, green and brown. Thanks in advance!

This Tachograph have only 4 wires? I think, it was difficult to find that diagrams, but if you can.. check brown=ground, white + 12V..

Four connectors not four wires. On the first /white/ connector I found "+" and "ground" cables.
