    Hi guys,

    thank you for helping, I just want to make sure, what I do is right.

    So, all I need is a connector (Ps2 style connector (newer)), then I need to use 10k resistor, to soldier between the wire of pin 3 and pin 4 for the keyboard connector right ? After that just plug in the other side of the keyboard on motherboard right ? thank you.

    Umm, right. But if you have to ask the same question three times to make sure that you have figured out how to bridge two wires with a resistor, I'd recommend that you not only don't do it, but seriously reconsider whether you're equipped to install a PC in your car.

    There are lots more difficult and fuzzy things about installing a car PC than this three step, very clear tutorial.

    Would this also work with a ps2 mouse?

    why would you need to fake the computer into thinking a mouse is plugged in?

    what purpose would that serve...?

    No.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    A PS/2 mouse works similar to a ps/2 keyboard, but sends a CTRL-M so that it knows it's a mouse IIRC.

    Take a read at this thread

    Oh, it is for a completly different application. Nothing at all to do with carPC.

    I've tried twisting the stripped wires from the keyboard around both ends of the resistor (1/4W, 10,000 ohm) but it doesn't work.

    Does it actually NEED to be soddered? I've tried just putting it in the PS/2 slot of the motherboard, and it still doesn't work..

    can anyone give me a link to the kind of resistors used here, so I can make sure I'm using the right kind?

    Mine are Brown, Black, Orange and Gold (color stripes)

    I honestly don't see how the OP's hardwire method will work with a PS/2 keyboard. From what I have read, a PS/2 keyboard with talk with the motherboad controller back and forth to and uses an initilization sequence to confirm the existince of each other. I am not sure that just using a resistor to drop the voltage across the +5v line will do anything (maybe for an AT style keyboard). My advice is to basically get an old PS/2 keyboard, tear the driver chip out of it and solder it the PS/2 cord. I had to do this with a mouse for my problem in my earlier post and it works like a charm.

    Here is a 10k ohm resisitor:
    Brown, black, orange, gold

    Are you sure you have the right wires to the right pins? Did you use a multimeter to confirm you have the proper wires or did you guess?
