I have a sony xplod cd player and I need help wiring it to a 1993 chevy fullsize pickup. I know that the yellow wire coming from my cd player is the memory and the red wire coming from my cd player is the hot wire. There is a red and yellow wire coming from my truck and I connect those wires with the red and yellow from my cd player. I have an orange wire coming from the truck and that is the battery. When I connect it to the yellow wires it turns on but when i turn off my truck it stays on. And when i connect it to the red wires it doesnt do anything. I also have a grey and white wire coming from my truck but i dont know what those are for. Can anyone help me?????
