This harness is replicated from a geniuine Tri-Z harness. All wiring and connectors are a direct fit. There may appear to be one extra black wire in the front of the harness. Yamaha piggy backed one wire out of a female bullet and put a male bullet on it. For a cleaner look i did that internally. Just take alook at yours and count male and female bullets and you will see that its a match. Thank you for looking.
