the three red wires crimped together and the three black wires crimed together need to be connected to your factory sidelight wires on the cars loom.
the bottom connector you've circled is the indicator so just use the standard one on from your standard headlights and the top one youve circled is for an extra sidelight which will come on with the rings. imo it looks better not to have it wired up so your sidelights are just the rings and no other lights

hope this helps.
