trailer lights

I bought a converter for my toyota for the trailer light connector i put on my boat trailer. I'm trying to hook the converter to my Toyota. I don't know which wire is which by looking at the colors. I need a diagram or translation of the wire colors to left turn, right turn, brake, ground and park/tail. I have a 1991 Toyota regular cab 4x4.

Check the FSM thread stickied at the top of the main page. The FSM will have a wiring diagram. I don't have one handy to tell you.
