Yep plug in the usual main 3 plug into the back of the outer lens. Sidelight fits straight in.
Then to connect up the middle lenses nearest the grille there should be 2 black wires coming out of the back which need to be connected.
One of the wires on the main 3 plug is an earth so piggy back off that onto one of the black wires from the other lens. Then with the other 2 wires on the 3 plug is powered for dipped beam, and the other receives power with full beam so piggy back off that onto the other remaining black wire from the inner lens.
The best way to piggy back is to get the piggy back type spade connectors
