    Steering Wheel Control Help

    I'm a little confused on hooking up my steering wheel controls.

    Car is a 2006 350z.

    Steering wheel controls are 2-Wire Resistive type.

    Pin 16
    Power (Press and hold POWER switch.) Approx. 0Ω
    Seek down (Press and hold SEEK DOWN switch.) Approx. 165Ω
    Volume down (Press and hold VOLUME DOWN switch.) Approx. 652Ω

    Pin 20
    Mode Press and hold MODE switch. Approx. 0Ω
    Seek up (Press and hold SEEK UP switch.) Approx. 165Ω
    Volume up (Press and hold VOLUME UP switch.) Approx. 652Ω

    How should I hook this up? Please in laymen terms.

    What were you measuring? Pin 16 to ground? and Pin 20 to ground?

    Nice! I can help but I'm not home right now. I will in the next day or two, rest assured.

    you'll need two resistors, that's it. I'll post info later

    Much appreciated mated. My installer just gave me a blank stare when I handed him my CarPC and Fusion brain..

    Thanks. I have read that thread but I don't get the wording.
    And your steering wheel is R2. Connect one steering wheel wire to ground, and the other the steering wheel wire to the input of the brain and one side of R2. Connect the other side of R2 to the +5vDC pin on the brain's analog input header (towards the center of the board). You're done!
    So one steering wheel wire goes the Fusion Brain ground (does it matter which?)
    Then the other goes to the brain analog input and R2? I'm connecting one wire to two places?

    Look at your service manual. Pin 17 is shared by the two steering wheel controls... is it has to be ground.

    Pin 17 to ground
    Pin 16 to FB input and R1
    Pin 20 to FB input and another R1

    tie the other sides of both R1s to +5vDC on the FB.

    make sense?
