Firstly I think the red-white stripe wire from my bike is the one connected to the fuse(in the picture that I uploaded, the last picture), I am confused whether the brown wire or the red-white stripe wire on the regulator should connect to the red-white wire from my bike. Then where will the last wire go?
Yes, unfortunately, to use the used factory reg/rec from ebay, you will have to add the brown wire. The brown wire of the regulator/rectifier would have to be connected to the brown wire of the ignition switch or the yellow wire of the ignition switch.
The red/white wire is always connected to the main fuse and the battery, so it always has 12v on it. So it cannot be connected to the brown wire. The brown wire should not have volatge on it when the ignition switch is turned off.
The output wire of the reg/rec goes to the red/white wire. That wire is connected to the battery so it will always have voltage on it. That is the what is connected to the red/white wire in your photo.
The Oregon unit, and the Shindengen SH775 unit do not need the brown wire. So they are simpler to install, but do cost more.
