hey guys im installing a car pc computer and the power supply has 3 terminals

ground
12v
and ignition

where under the dash can i find the ignition wire "exactly" and waht color wire should it be

its under the steering columb isnt good enough alittle more descriptive would be a big help

thanks guys

 

How much power does it draw?
The pink/black wires that you'll find all over the place are fused with 20A I think. Or how about taking it straight from a terminal in the fuse box? There are both constant 12V and switched 12V outlets there.
Wiring diagrams can be found at autozone.

 

ok thanks i'll take a look into it

im not sure how much power just knwo its made to be installed in cars and requires 12v ground and ignition signal cuz its a smart power supply that is supposed to slowly turn on/off teh computer so i'm guessing it needs the ignition wire to get that reserve power so teh computer isnt instantly unplugged so to speak
