Hmmm... Beats me with a stick! My initial impression is that it looks like an 1157 bulb receiver. But if it's a female receiver looking for it's male counterpart, then I'm wrong. Maybe someone will be able to ID this thing, although instinct tells me you're going to need to go to a wiring diagram and simply start sorting things out. I lucked out yesterday and all my lights are now working. Can't say exactly what the trick was other than individually opening and cleaning (CRC contact cleaner) all connections bullets and terminal blocks, in and around the nacelle. Put a little pinch on all the bullet connectors to assure wiggle free contact. Tiny needle nose pliers will help with removing / pinching / installing the bullets, so you don't stress the wire by simply pulling on them. Wiring diagrams aren't so bad. Study them until you're confused, then go back and do it again, then again. In good time I will open up and fully photograph the blinker switch and start button switch for a thorough cleaning. BTW, yes, there are two wires (each) going to the front lamps. One is for blinker the other is for running lights. On my bike they are both black. Another thing is that for the blinkers / running lights to work, the ears need to be grounded (bolted) to the nacelle. With the nacelle removed you need to provide a ground directly to the individual ears.
