Hello Bob,
You can continue to use the Canbus connection for the constant plus and minus connection. If this causes malfunctions on your Canbus system, connect directly to the battery. So this applies to the black and red wire.
The yellow wire must be connected to a ignition wire. So the ignition of your bike is on, voltage is present on the yellow wire. The bike’s ignition is off, there is no voltage on the yellow wire.
