    no, you shouldn't need any other resistors.

    What you need to do is set your volt meter to measure DC volts, in the range of 15 volts or so. Then, attach the positive lead of the MM to the brown wire, and the negative lead of the MM to a sutiable ground, or the negative terminal of your battery. Then, press different switches and write down the voltage you read for each one. Post those here.

    thanks, will do. my mm has 200m,2000m,20v,200v,1000 on the dcv. can I just use 20v? and by looking at the wires on the page, I think it the green/red wire instead of the brown. I think the brown is for navigation controls. after finding the voltage of each, would I have to buy resistors?

    20v, means it will display anything up to 20v with the correct decimal placing and such. Its not an auto set multimeter apparently.

    My guess is you will need to buy a resistor as I have explained in the PMs.

    Is that just for one button? I have three buttons on the steering wheel. for each button, do I need to use three digital inputs on the fusion brain?

    Ok, there are 2 ways of doing things.

    First way, every button goes to a digital input. For this, you solder to the actual button wherever it is. If it is the steering wheel, then you will have to be careful of the wires twisting.

    Second way, is to use the factory steering wheel control. This sends all buttons on 1 resistive wire. Depending on what buttons you push this one signle wire changes values. Just like the schematic says.

    So a bagillion buttons goes on 1 wire. That is what you measure to an analogue input.

    I think you are confusing things. This works just like any other steering wheel controller.

    Okay, Im understanding now. So the 2nd would be best in my case. Then I would just use the analogue inputs which would be three of them to the steering wheel resistive wire. use a MM to find the voltage of each button press on the resistive wire. right?
    now since Im going to use the analogue inputs which are 3-pin. I only have one 3-pin
    input wire. can I use a 2-pin wire or do I have to order 2 more 3-pin input wires? thanks

    okay the resistance for buttons are as follows, no buttons pressed the wire reads 3.9
    and the first button, when pressing the vol-up 1.08, vol-down 0.37, 2nd button ch button, it reads ch-up
    2.66, and ch-down 1.82 . the third button is the mode button, fm,am,cd,aux anyway it was 3.39 when pressed. those are the valuse for the three buttons. Now, what resistor do I need or the next step? thanks

    those are the resistor values right in ohms?

    What are the voltages?

    yes, I thought that they are the voltages

    those are the voltages of each button I pressed.
