I just bought a use radio (sony-cdx-l510x) no direction.Where does<orange-dash lights><orange&white-dimmer>yellow-battery constant><12voltpower ignition> what goes where?

when will people learn to buy the damn metra or scosche harnesses? It's the best spent 20 bucks EVAR~! I could get into telling you how to use a volt meter and a 9 volt batter to figure out your cars harness, but the nice guys at metra already did it. BUY THE HARNESS.
