I have the rLink and love it. I use the information from this post:
Scorpio Alarm Install
I did not use the wiring harness, just spliced into the tail light since the harness was not available in May 2011. Also, I taped(double-sided) the cellular antenna to inside tail fairing close to the tail light. I would call Scorpio, I assume the harness should work but nobody would know. To tell you the truth, if you order the alarm from most sites, they give you the harness for free.
