I have just completed the installation of this unit on my bike. I had an Audiovox and when it broke instead of replacing it, I decided on this unit. I used a Rostra 250-3592 control instead of the goldwing part.
This control is momentary, so switch number 12 has to be set to "open"
This is the diagram I drew for installation:
I have run and passed the diagnostics test except for one problem- I'm getting a signal from the vss that is causing the LED to blink. It turns out that you shouldn't leave your battery on a battery tender while testing the bike. When I disconnected it, the pulse went away. I'm assuming that the battery charger pulses in maintain mode.
I'm out of town for several days, but I hope to find out if this works soon.
Edit: Works great. Nails the speed and holds it rock solid.
