Appendix B: Resistor Kit
Some vehicles have a separate wire for each of the steering wheel buttons. Use this resistor kit for the steering wheel push buttons that do not already have a resistor network connected to them. Examples are Nissan and Harley Davidson motorcycles.
Connect a resistor to each side of a push button and connect the other ends of the resistor all together. Connect the SWI- JACK to these resistors. On the Harley Davidson, one button can be connected directly to the
