    powering the screen

    Ok so the screen came with a power kit that plugs into the cigarette lighter. Is there anyway to directly connect the power to the car so when the car turns on, the screen turns on so I don't have to plug it in through the cigarette lighter?

    anyone have diagram for this?

    Cut off the cig lighter plug and connect it to 12v switched line & ground.
    Have you looked in the FAQ yet?
    How about the Wiki?

    well i still want an open cigarette lighter, I dont want to completely cut it off. Maybe there is a way I can splice into it? Behind the console?

    after cutting off the end of the power cord, just keep the lighter end, so that later you can heat shrink it back together.

    just tap into your headunit 12v wire. Use a blue t-tap connector. just look up the color code.thats what I did and I have a xenarc 7''tsv monitor. but to get no buzz or faint lines in the screen and years of good performance, better to use a little power supply. Which im going to get a opus p.o.l 15watt. I think it around $30.00. multiple monitors or 10'' monitors or bigger, you have to have one.

    I think you misunderstood.
    Cut off the cigarette lighter plug on the LCD power cord, not the cig lighter in your ride.

    The t-taps (or vampire taps) that someone else mentioned will work just fine. Tap into any switched 12v power line.

    reading the specs on the opus pol it says the input voltage must be 1.5V higher than the output voltage. when my car's engine is running, the alternator puts out around 14V but when the engine is off, the battery only puts out around 12V. does this mean that if i hook up a screen through this thing, the screen will not power up when the engine is off?

    Ok, and let me make sure before I go cutting wires. all i do is , cut the cig lighter end on screen with wire cutters. Strip it so wire is showing, attach it to 12v line?
    is that how I use one of those vampire cutter things?
    Or is it simpler?

    yes cut off the cig lighter plug to the monitor. and attach it to 12v line.when you find the line, you can tap into it w/t-tap. or strip the 12v line wire back, twist the + wire from the monitor wire around the 12v line in the radio harness.

    Ok so I dont have to deal with negative and positive? I can just attach wire to wire?

    Screen lighter cord -----> 12v cig lighter in dash
    WIRE---------------------> WIRE
