    Any thoughts before I move forward? Audi a4

    Here is my computer setup, it will all be mounted in the glovebox.

    Xenarc 7" LCD VGA Touchscreen 700TS USB
    VIA EPIA-M10000
    DVD ROM
    SB USB MP3 +
    256 DDR RAM
    60GB Hard Drive
    Power Suppy - VIA EPIA-M 12v DC DC 120W PSU Car-PC Mini-ITX

    -----------
    Blitzsafe - This will hook the sound to my audi sound system

    Here is were I may need help. This is a diagram I made (reda4 helped). Does anyone see a problem with this diagram? Am I missing any wires? WHAT ARE THE WIRES CALLED THAT are used to give power to the PSU and Monitor? Anything will help, thanks

    Also, I know I should use opus power supply, but i wont be using the carputer evertime i drive because i do mostly 5-10 minute drives and there isnt a need to power it up. But i think i will eventually upgrade to it

    anyway. looks good to me, but, i didnt look at the PS you have selected. my comment there would be to include an ignition switched relay to cut power to the computer, so you dont kill the battery by leaving the computer on when the car is off... this brings up the option of a shutdown controller. you may want to include a shutdown controller to tell the power supply to shut off after X minutes. basically, a smart version of a relay.

    How are you powering the screen? You can do it either from the power supply or from the car battery, you need to research and decide, I've done both on my setup.

    The wires are called "Wire," I recomend 10 or 12 gauge.

    How would I go about powering the screen to the power supply on my computer? Would it work with the psu that I bought?

    Thanks!

    Do what I do, and hook up the remote power line to the Opus to a switch which you put in your dash Allows you full control over when the Opus turns on/off, not just dependant on your ignition being on

    Works brilliantly Also the advantage that you can turn it on without the ignition on, and when you start the car if you DO go anywhere...the computer won't reset

    Assuming your screen takes 12v, tap the positive and negative into a pair of yellow and black wires respectively off one of the molex pigtails that is supposed to go to disk drives and cd-roms and stuff. But if i were you, rather than risk blowing your isht up on my say-so, go invest in an $8 multimeter and double check which wires have the desired voltage (I'm right though, heh...it's how i run mine at the moment)

    Edit: here, for clarity, is a similar diagram i drew of my setup:
