HELP! V6 w/premium stereo

OK, bought a new head unit because stock one (Premium CD stacker) locked up on me when battery ran flat. Cut wires to get it out. Problem now is I can't find the ignition wire (don't know colour) it's not grey. Excluding speakers i am left with: Grey/white, green, blue/red, red. I have been using head unit with its ign and pwr connected together with the blue/red from car but it resets head unit every time i turn the keys, does anyone know what's what???

The radio needs two sources of power. One turns on with the ignition system the other is constantly on. The reason the radio is resets is power is being lost to its memory.

Try Red = Dome light (constantly on power), Blue/Red = Cig/Radio (ignition source)
