Good question, I have this same question but for my 98. Bump for an answer.

 

Going to a friends now gonna use a multi meter on it. I'll update you

 

I forgot to right down the wire colors but ill get em later. Basically if you pull the plug out, standing in front of the car, the ground wire is the right side of the plug. The low beam wire is the top socket of the plug and the high beam is the left socket of the plug.
