Hey timnc, sorry I didn't get back to check this thread sooner. I was delivering my daughter and a truck full of her stuff to college.
Glad your problem was the ground connection. That's an easy fix.
Just a word of warning if you connect the brake lights so that they change the delay for the turn signal shut off. The 3/16 spade connectors on the brake master cylinder are thinner than normal. I bent one when I installed my "Y" wiring adapter. I was able to bend it back, but I don't think the switch's spade connector will survive too many bendings before it breaks. Then you'd have to replace the switch assuming you can buy it without having to buy the entire master cylinder.
I didn't hook up the running lights option. First, I don't think that full time turn signals acting as running lights help visibility all that much with a full time head light and the nice Versys LED tail light. Second, I couldn't find a way to tap into the turn signal wiring without cutting into the harness. Third, I didn't like the idea of the dashboard bulbs being lit all of the time. Fourth, I was also concerned that the incandescent bulbs, if on all the time, might eventually overheat the turn signal lenses and discolor them.
While I've had to get used to it I like the turn signal cancelling. Before I had it I would often forget to turn off the signals and drive for miles. Just too much noise when riding, and I don't constantly look at the instrument cluster. I felt like an old man whenever I left them on, and sheesh, I'm only 55.
