Found this in the headlight assembly its a light blue in colour but everything seems to work on the bike with it not connected.

Appears to be a little teeny extension cord. If everything works I wouldn't worry about it, just don't throw it away.

According to the parts fiche it looks to be a ground wire for the turn signals - Part # 33605-310-000 - SUB-WIRE, TURN SIGNAL GROUND. Is the connector under that rubber sleeve for two wires or one?

it is a single bullet connection.
