I connected the GPS/Fuel Harness to the 6YC Info Center Gauge and installed a Moeller 2 wire reed type switch on my tank. All hub inputs either have a power harness, buss harness, device, or cap. The entire system is powered from the single power harness within the console. I capped the 2nd hub's 2nd buss input with a grey terminator cap.Įach hub has one grey terminator cap and one end of the buss harness plugged into the buss inputs. I capped the 2nd hub's 3rd device input with a white cap. I connected the gateway harness between NMEA-2000 backbone & the 2nd hub's 2nd device input using a CL pigtail. I connected the gauge pigtail between the 6YC Info Center Gauge & the 2nd hub's 1st device input. I connected the 1st hub to the 2nd hub using the 1st hubs last buss input and the 2nd hub's 1st buss input. I connected the power harness between the remaining yellow ignition wire and ground & the 2nd hub's power input. I capped the remaining two device inputs on the 1st hub with white caps. I connected the two pink leads beneath the motor cowl next to the white CL block together to turn my tilt/trim data into digital rather than analog signal. I connected the engine harness between the engine connector block and the 1st hub's 1st device input. I capped the 1st Hub's buss input with a grey terminator cap. I capped the 1st hub's power input with a red cap. I am describing the Yamaha CL Hub inputs from left to right. NMEA-2000 backbone, T's, terminator's, drop lines, etc.ġ Yamaha GPS/Fuel Harness 6Y8-8356N-01-00 Here is the system and components I'm working on for my new boat: There are no device to device pigtails that length. The reason 2 hubs are required for most every installation is that the only harness long enough to run between the motor and the console is the buss harness which is 25'. The pigtail used at the engine is long enough to run through a rigging sleeve or hose and connect to a hub mounted within approximately 18-24' of where it passes through the deck or hull. While I describe the device pigtails, harnesses with the white 4-pin device connectors on each end, with the function they serve in my installation, they're actually interchangeable with each other barring length issues and the different part numbers are simply denoting the different lengths. Each system requires its own power source and each is limited to only one source of power. When CL is connected to a NMEA-2000 backbone, it does not power it and neither will the NMEA system power the CL system. If CL is to be connected to the NMEA-2000 system, it will require the Yamaha CL Gateway Harness and another short device pigtail to connect the gateway to a CL Hub. Much like the the NMEA system, CL must have power, connections to a main trunk, and terminators. If you come across something that is incorrect, please let me know so we can edit the post to help others that may read it. I believe I'm only a few questions from having this thing figured out.Īny help you guys can be would be greatly appreciated and perhaps this post could serve to help others with the necessary components and wiring of the system! At this point I believe I have figured out that the Yamaha Command Link is simply a propitiatory version of the NMEA-2000.

It appears Yamaha only provides instruction manuals with kits so I've had to dig for information online at a time there is very limited information available. Unfortunately, I did not understand there were kits so I purchased my components separately. I have purchased one of the new 6YC Command Link Information Centers.
