Just took it off of my 2002 C10 while working on other projects.

The modulator works perfectly, never had any problems with it. Comes with original wiring instructions.

Asking $40.00 plus shipping (I am in Peterborough, Ontario, Canada).

Make me an offer if interested.
(Let me know your location, so that I can check shipping cost.)

Thank you,

Las

Does this work on multiple bike types or just the C10?  Please update the subject line with the bike it's intended for.  Thanks.

Thank you, Jim for warning me. Actually, the modulator works on any bikes.

Also, on the other forum there is a great article on a non-permanent installation method: http://cog-online.org/clubportal/clubstatic.cfm?clubID=1328&pubmenuoptID=30605
