+2 on the front brake light switch. Even though it is not required, it would be nice if the switch were included and the wiring in place. Not worth the trouble to me to add it but if it were already there, I'd potentially set it up. I did set my bike up to make the OEM tail light work as a brake light to, as the function in the light is already there and the wire to the plug exists. I sourced a pin for the plug and jumpered to the BD harness to make the OEM light function when the BD kit is not installed. You say other manufacturers of DS kits use the OEM tail light? Who, as I'd be interested is contacting them. PM or post here, please.
