Headlight wiring

[DJN]

Can anyone explain this wiring; to a replacement headlamp plug on my Inazuma ?  Replaced by a local bike shop  when the original plug melted.  Both main and dip lights have now stopped working. 
 The green wire (common) connects to two black/white wires from the loom and the blue (high beam) to two yellow wires. Not sure what  the white (dip)  connects to. I have measured 12.8V  at the spade terminals  for dip and sporadically 12V for high with the high beam switch on.  But a known good bulb isn't lighting on either setting.
  I have ordered a new H4 plug (with pigtails) that resembles the original. I am a bit confused, as to how to wire it up by the existing "2 into 1"  setup.    revealed

  ...so I got my replacement headlight plug wired up correctly . The issue with the headlight not working was caused by damage to  a nine pin connector located below the tank.

      This connector serves *all* handlebar switches;  so it is worth checking after the more obvious causes of switch failure.
