This is our NMEA Power Cable.
With many fish finders, their NMEA 2000 interface will not transmit or receive data if power is not presented at the NMEA 2000 port. In other words, almost every NMEA 2000 networks needs to be powered by one of these.
This NMEA power cable comes in a model that includes a standard 7A fuse. This is important to protect any of the wiring in your NMEA network. However, there is also an unfused model. This version is for boat owners who have existing unused fuse holder locations under their dashboards.
You have three options for where to connect to +12V. Firstly, you can connect this cable to positive power either on your accessory switch. Secondly, your engine ignition key switch. Or thirdly, directly to the battery. Therefor, you should choosing one of these three options depending on when you will use your trolling motor and electronics versus when the main outboard motor is running. Typically, people connect their NMEA power to their accessory switch.
Consider if you may want to use other functions of your NMEA 2000 network when your trolling motor is the only motor running, and not your outboard. Based on this, it may a better idea to wire positive on this cable to your accessories switch, and not to your engine key.
This cable is 3 feet (1 meters) long, from the Tee to the flying leads.
If you are installing this power cable under the dash of your boat, to your NMEA Network from your ACCESSORY switch, or fuse box, and need a shorter length, you should check our Better Connected™ NMEA Power Cables. Located here:

These cables are made of the best components and construction. For example, there is a heavy duty braided shield under the black outer jacket, and then there are foil shields around each of the 2 wire pairs inside the cable. All together, there are 3 shields total, plus there is a drain / ground wire for additional noise elimination.
You cannot buy a better NMEA cable for this price.
