OK I will admit I am a newbie and this is probebly a very easy question for most of you, but I need some help. I am installing an older (1999) Pioneer radio into my truck and the original instruction manual is long gone. The model # is KEH-P4800. I need help figuring out which wires go where. I know yellow is Batt. and red is Acc. and black is ground. What I need help with is figuring out which speaker wire goes where. There is gray, white, green, and purple. Which ones go to the front, back, left, and right?? THANKS for any help!

1999 is when Pioneer adapted the eia color code Kgerry referred to: https://www.the12volt.com/request/request2.asp. Pre-1999 Pioneer color codes can be found here: https://www.carstereo.com/help/radio_wires.cfm. ------------- My ex once told me I have a perfect face for radio.
