No special tools, assembly description is very detailed. The color coding of the wires should be considered. To ensure that no twisted cable arises are to consider both ends of the line and equalize. I have this plug with connectors (Digitus or BTR) on Cat connected 7 Cable and so carried out the house wiring from the central router to the individual terminals (PC, Internet radio, notebook etc.) in different rooms and floors and thus bypassed the wobbly WLAN.
