The red wire goes to the inst.light fuse and the black wire goes to the B/U light fuse. This will turn on the buzzer if the headlighs are left on and the ign. is turned off. Remove the fuses then remove enough insulation to wrap the bared wire around the fuse end and replace the fuse. I wrapped the wire around the fuse end that is away from the center of the fuse panel. This is the fuse protected side. To the right of the original is an extra fuse panel that I added.
