It's actually very simple.. Remove your taillight lens and you're almost there. Unscrew both lamps and plug the little tail light bottom piece that attaches to your new light into the right lamp hole and if all you want is the tail light, then yer done. Turn on the key, check it out.
Now, if you wanna incorporate the turn signals, each of the yellow wires will be required to be spliced into the Hot wire going to each tail light. You can figger this out by..
1. Key on.
2. Turn on a turn signal
3. Go to the tail of the motorcycle and disconnect one of the two turn signal combinations you've mentioned. Did the turn signal go out? If not, try the other one. Once you've identified the correct connection, take a multimeter and identify which wire is the HOT wire. Test toward the harness, not toward the turn signal.
4. Turn key off.
5. Splice one yellow wire from your new taillight into the hot wire going to the turn signal. Key on, test it. If it blinks too fast, The instructions show you how to wire in one of the included resisters to change that.
6. Crack beer and admire your shiney new LED taillight assembly.
