Wiring help

Just purchased a 2007 SMR 510. Love the bike so far, but it has some issues the previous owner left for me to deal with. There's no head light or blinkers. Just bought a universal Polisport headlight and some universal led blinkers. I'm assuming I need to splice a 3 wire H4 bulb pigtail onto these wires-1st thumbnail. And I'm assuming these 2 are maybe the switch wires(there's a 2 wire pigtail off the back of the Polisport headlight assembly)-2nd thumbnail. And last, is this the blinker relay? Noticed a wire has made its way out of the connector.-3rd thumbnail. There's wires taped off that say left and right so I'm hoping those are the turn signal wires.

I don't have much wiring experience so this is all sort of foreign to me. Thanks in advance!
