There will usually be a plug for tail lights under fender. Before hacking several wires, look for the brake light plug, get a good visual of it or better yet take a pic, go to
http://cycleterminal.com and find the type plug you will need to make your own plug and play, they will send you male and female plug that matches along with the pins to make your own harness. You can now plug and play without butchering the OEM wire harness....maybe.
