Hi!

You only need to connect to 2 of them, I think it is the 2 to the left.
Black and a white connector. Measure on them, one of the connectors is powersupply to the interface +12V and ground, I think the white is signal but I don´t remember.
If it dosen´t work just shift the signalcables, Don´t connect the powersupply in the wrong way!

The powersupply connector is keyed at the short side, the signal is keyed on the longside (cut corners).

Just to clearify: use 2connectors (4cables/connections)
