I am installing a Rostra universal cruise control on my R1100RT and the universal button control has a grey wire that I don't have a clue where it goes? The unit looks like this. http://i48.tinypic.com/j5xbhs.jpg You can see the grey wire quite easy in the photo.
My button system did not come with any wiring instructions (Probably purchased it 6 months ago and now finally installing it.....) all the wires are really self explanatory except for that one when reading the rostra installation manual. Anyone got ideas? I think it might be like the pink wire on some other universal units.
I'll go hook up the other few remaining wires and check back later.
Thanks for your help.
