Red Wire - Brake (+)
White Wire - Park (+)

I think the question is probably about the bike's wiring colors, in which case:

Yellow = brake light
Blue = running light
Black= ground

at the tail light connector.

I believe those are the colors coming out of the the motodynamic light, NOT the wires in the Yamaha harness. That is also consistent with their diagram. The instruction sheet is not clear on where to connect things unless you're just plugging in directly to the Yamaha connector and doesn't seem to provide any detail about the colors of the Yamaha wires.

Typically black is ground. Should be easy enough to figure out which is which with a simple multimeter and a bit of trial and error.
