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

By putting two or more resistor in series, you can come up with additional values. Ex. 150 + 1000 + 1500 = 2650ohms.
