I used Mick's write up: http://lindleyonline.com/goldwing/cellphone.htmWhat 3-wire harness are you using Wichita Scorpion? I have had a couple of us working with a Palm Centro and have not been able to make things work. When we make connections, incoming voices are great, out going voice is ok. When the bike is running, incoming voice are great, but no one can hear me talk. I do have a Compufire if that makes a difference. Do you have any suggestions?
