According to the manual, you'll need to tap into solid green for the left, and solid grey for the right side signals. The solid orange is the common feed from the flasher relay.
You will probably need to use a pair of diodes if the alarm kit does not have two separate leads for the signals.
I have come to terms with the possibility of dying while riding, life has a 100% death rate. I would rather live having fun and end up dead in a motorcycle crash than never do anything fun because it's dangerous and I might get killed. No one makes it out alive anyway. - From a friend on another forum, used with his permission.
