Power To My LCD From PC Power Supply
I Just Bought a Serial LCD From Crystal Fontz ,a 4x20
http://www.crystalfontz.com/products/634/index.html
and they said the LED hooks up to a spare PC power supply connector to LED backlight Cable (WR232Y02) one of th accessories they sell. My Carputer fis in my trunk, which is about 15 ft. to the dash, where my lcd is. Is there a way i can make an extention kind of wire that will go from my dash to an extra power connector from my PC's power supply? What Kind of wire would i use if i wanted to cut the old wires and make an extremly long kind instead
Thanks as Always, and Happy Holidays

Ive already split the wire to the cig adapter about 3 times, for my inverter, for my cell phone stuff. Is there any way i can just buy two wires to connect the two things?

I've had my tapped into the wires behind the cig. lighter forever. Not one single problem. If the LCD controller is any good it will take care of voltage fluctuation.

I won't start an argument, but I highly doubt there are any controllers that would be happy with unregulated voltage...

ppgt94 i guess your simply lucky ... but dont push it .. cause LCD's are very sensitive electronic devices and its better to have regulated supply .. for them .....

in other words, use the connection from your computer (the picture I posted...the connector is called a "molex connector"..) and yes, it should be ok to make a long wire from your power supply to the lcd.

Please excuse my ignorance.
Wow, you guys kinda opened my eyes I looked at my controller spec sheet ( http://www.zlcd.com/downloads/NL6448AC2006.PDF ) says the supply votage should be 4.75v - 5.0v @ max 1A. I've always used 12v regulated and unregulated (from car). Hmmmm... 
I wonder if I've killing it?????????????
