Custom Project - What Wires Do What

I'm installing 3 gauges where the factory cd player was installed. I want to use the wiring harness that originally pluged into the cd player to power, light and ground the gauges. I've found the constant power, ground and illumination wires, but can't find the wire that only gives power when the key is in the on/acc position. can anyone help?

Use a volt meter and check them all with the car off. Then do it with the key in the on/Acc position. You will get your answer.
