I've installed one on my79 R65 last week and so far I am liking it.
I connected 3 additional wire (included in the kit) so now I have runnin lights, 4 way emergency lights and by hooking one of the wire to brake light you get the brake flash option (turn signal will flash
for 2 second when yo hit the brakes) and also suspend the time out features of the turn signal till you release the brake (very useful when you're stop in traffic light waiting to turn.
I changed my rear amber lens to red ones to comply with existing law.
There's a guy in E-Bay selling these red lenses (I think $15.00).
Because of one switch (Right, Cancel. Left) I still have to figure out
how to automatically go to Cancel once I hit either Right or Left signal.
Kit included to springs to install (havent done it yet). Hope these helps....
