    Thanks so much for your advices, I will try to build this tomorrow. Does this looks correct to you?

    That looks good. Try it out and see if you can get it to calibrate. If not, you'll need to use lower resistor values.

    Man, it didn't work. Window cannot detect the gamepad, I've tried with no resistor, w/ 100k ohm resistor and as well as 560 ohm resistor.

    So how do I figure out what resistor value to use, do I need to match up the resistance level of the steering wheel to the analog stick?

    I measure the resistance values of the analog joy sticks.

    Stick posistion__________Resistance
    ------------------------------------------------
    Left __________________10k ohm
    center_________________50k ohm
    right __________________90k ohm

    Steering wheel _________Resistance
    ------------------------------------------------
    Up____________________177 ohm
    mode___________________15 ohm
    down__________________700 ohm

    Can someone give some advice, I am total noob when it comes to electronics.

    Check your USB connections. I just tried mine without the analog stick cable connected, and Windows still recongizes it, so the gamepad could be damaged or a wire is broken on the USB side. Or something shorted. It's easy to just short a couple wires and it's all gone.

    Well, when I cut the 5 wire ribbon cable between the main board and the analog stick board - Window will not see the gamepad.

    When I reconnect these wires again then Windows will see the gamepad.

    Or

    Connect input wire 2 with 3, and input wire 4 with 5. Then window will detect the gamepad again.

    ======

    In my setup, I only need two axis. Therefore I connect input 2 + 3 together so that takes cares of one of the stick. Then connect the wire from SWC to input 4 and input 5. then I use the 10k ohm resistor.

    Oh, that's good then. Was hoping nothing bad happened. OK, so you've got pins 2 & 3 covered, but it may be better to use those 100k resistors between 5V and each pin. Are you sure it was something like this?
    5V - 100K - pin2
    5V - 100K - pin3
    5V - 100K - pin4
    5V - 100K - pin5

    If Windows recognizes the gamepad, you'll need to keep all that since it doesn't work without it. This would keep a voltage on each pin so it always works and pin 2 & 3 won't get any noise.
    At this point, you can connect 5V to #25 (although GOC says use a diode there - probably important). If that's grounded it'll short though. You sure that disconnects from ground? I hope so.

    If it all works, something like this should give you a huge change when you press a button. If all the buttons show -127 in calibrate you'll need to reduce that 100K on pin 4 and pin 5 (a lot).
    5V - 100K - pin2
    5V - 100K - pin3
    5V - 100K - pin4 - 560 - #22
    5V - 100K - pin5 - 560 - #23

    This is how I am connecting now...




    So I picture this is what you are suggesting?



    Or like this?




    ================================================== ====

    BTW, is the idea trying to match up the resistance of the steering wheel control to become the same as the gamepad? In this case, here are the resistance of the two. What do you think?

    [GamePad]
    Stick posistion__________Resistance
    ------------------------------------------------
    Left __________________10k ohm
    center_________________50k ohm
    right __________________90k ohm

    #3 looks rights. You can't really match the gamepad, so you have to change the whole scale of different resistances. The problem is that it's way off from 10k~90k range to 1~700 ohm, so with the normal joystick port we just scale down the resistor math, but with that gamepad not having the normal ground it might be more difficult. So now we have 10k as a default value when the gamepad starts up which I think would change the 10k/50k/90k range to 2k/10k/18k. When a button is pressed now it will be 10k parallel with (560+15/177/700). That's below 2k. Those bottons may all show the same value. Damn, the 10k would be much better if it was 5k or less, but would the gamepad still work?

    I have confirmed that the connects2 is actually working by connecting it to a sony radio - no problems here.

    The Connects2 i got is a DPGS003 - Any idears ?

    Thanks
    Anyone ever have any luck with this? I'm thinking about doing this to interface my steering wheel controls with my carputer without ripping up the car wiring loom. I've had a Connects2 adapter running on my Sony h/u for ages working great.

    Not sure if this has already been said as I've just jumped to the last post.
    I've been using a sony joystick to control winamp for 3 or 4 months now and once I got past a few teething problems it works great. All I did was get a joystick plug and wired it up to a headphone socket & 2 risistors. I've got a winamp plugin and now I can control winamp without having to always use my screen. If this is any good let me know and I'll dig out the schematics and the winamp plugin. All my mates think it is a cool way to control winamp and are puzzled to how it works!
