Wire colors
You might go into the tail light and get the color codes off the wires and then decide where is best to pick off wires. I believe they all go through the tail light. But can also be picked up under the seat once you have the colors.
Here is a link to a shop manual, but I do not know all the abbreviations for the wire colors.
