1. The wires on this hotend may be a little shorter than your current hotend. If you find this to be the case, pull the extension wires (the wires that run to the mainboard) down a little bit in order for them to reach. 
The hotend that came with your printer may have a bead of red RTV silicone around the top of the hotend assembly to provide a snug fit in the extruder carriage. This hotend does not have the bead of silicone. If your hotend fits snuggly in the extruder assembly, the bead of silicone is not always necessary. However, if you find your hotend is slightly loose in the extruder, apply a small bead of RTV or similar silicone around top of the hotend. Keep the bead close to the edge to avoid silicone interfering with the filament path. Allow the silicone to partially dry (dry to the touch is usually good) and install the hotend. The silicone bead will compress and provide a tighter fit.
