The wires are so small, you don't need to use a resistor. Eelectric shields don't draw that much energy. I'd check the wiring diagrams, for any unused electrical connectors. That way, you don't need to interupt any circuits. On my '04 Venom, I used the reverse buzzer + wire; because I didn't have reverse. It was just open. On my Nytro, I plugged right into the accessory plug connector. Good luck.
Smile; it makes others wonder what you're up to.
Smile and wave boys, smile and wave.
