I believe it's 3 pin stock connector. The relay I received was the right size connector, but with only 2 wires. Plugged right in and worked perfectly.

 

so it's semi-fixed. I re-ground the wire, and sprayed the inside of the turn-signal-button housing with a special spray. No more weird lighting issues. I didn't swap out the flasher relay yet; so the blinkers don't quite blink. however, they do make great riding lights.

It turns out that the white connector for the day light or whatever is a ground wire. So I re-grounded my blinker wires from the blue and orange connectors into the white connectors. The turn arrows on display stop randomly lighting up. yay.

I can live with the blinkers not blinking. My relay is a 4 pin one. Ebay has some 4-pen led flasher relay for like $30+. Right now, the bike might be in need of a new ECM, and getting in good running shape is the priority.
