This wiring is for the standard audio system

So its a wagon? or I dont know what S/W is. If the license plate light works, the light failure sensor could be bad. It should be in the left rear corner area and have 4 wires. Green, Light Green, Yelow/Green and White/black. You should have power on the Green going into the box, and the Light Green out to the tail lights. If you have power on the Green, but no power on the Light Green, then the box is bad, either replace the box, or you can just connect the Green to the Light Green wire to get tail lights operating.

trick of trade... take a 9 volt battery and touch the wires to it.. the speaker will pop and you will know which one is which... do one color at a time

red light = 25%
Red + Green = 50%
Red + Green + Green = 75%
Red + Green + Green + Green = 100%
