Dual Purpose Bulb System
Right Turn & Brake Lights, Brown
Left Turn & Brake Lights, Dk Green
Tail Lights, Black w/ Yellow Stripe or Black
Ground, Black
Single Purpose Bulb System
Brake Lights, White
Backup Lights, Violet

just a note, i'm not 100% on this, the best way to test is to connect lead wires to a 12volt test light and hang it in a way you can see it from the drivers door, then hit the brakes and then the running lights
