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.Replied to you on FB, but posting it here as well for completeness
Red Wire - Brake (+)
White Wire - Park (+)
Black Wire - Ground (-)
