Been having trouble with various instrument functions cutting in and out (speedo, GPI, neutral light, etc.). The problem is individual connections coming loose. I studied the female plugs that are embedded in the two plastic plugs and found that they have two miniscule flaps that grip either side of the male post. So I painstakingly pushed the female ends out of the plastic carrier and pressed the tiny flaps together so they'll grip the post better. Not easy -- there is no extra wire and it looks all too easy to break a wire. But I had a nice little ride this afternoon and everything worked great.
BTW, I'd be posting more but I got married on October 7 and so I've been busy with family life :) In case you're wondering, my new wife loves my brick and loves riding with me. Life is good!
