I have the resistive network buttons in my saab and I get a voltage signal from 0-5 volts dependning of buttons pressed. I will use a LM3914 LED driver IC to translate the voltage into different pins. Those pins will go into optic couplers (right word?) instead of LEDs and the outputs will be used as switches for a hacked USB keyboard. I'll let you know how it ends up. Total cost will be like 15 bucks or so.
