my dealer gave me a 2011 Spyder 2011 catalog and here is what it says (pg 46 if you have one handy)
Combination harness: when combining the HID Xenon lighting system and the Fog Lights on your CanAm Spyder roadster, the following wiring harness is required. Spyder RS 219400089 ($99.99)
now i am not sure if this is in addition to the harness you already have, or just in replacement of, but i know you need the harness (my dealer ordered one for me and my :spyder
hope that helped some.
