Amp Capacity of MULTI Cable Buzzer and CAN Bus Outputs

What are the amperage out limits from the MULTI Cable:
Red 12v + wire to ground?
and
CAN bus white/red to white/black?

My question derives from a need to switch an external load [less than 250mA] to coincide with TZT2 on/off.
 
The canbus wires are INPUT not output. They are used when trying to power a small NMEA 2000 network connection without using a power Tee.

The red wire is for driving the external buzzer and only supports around 150 ma. It really isn't designed to be a power supply but you could probably use a it to switch on a suitable relay.
 
I tried doing that with the NMEA0183 version of the Smart Sensor depth transducer that returns only DPT, DBT, & MTW. It worked fine.
Ive now switched to the NMEA 2000 version a
FURUNO Smart Sensor DST800PV-N2. This derives it's only power via the 2K canbus.
