1. What is the reason for needing a 120A cap for the back bone? (I'm a Humminbird guy).

2. It sounds like people are saying I need to put a switch in the NMEA power line. Why? Does this continue to draw power even when the units are off? My thought was to connect everything (fused) right to the battery.

3. I noticed that when sharing the GPS, It also adjusts the brightness of both units by adjusting either one. Are there any other this that control both units?

Thanks again everyone!!!

1. 120A cap is the network terminator. The T connectors have basically an "in" and two "outs". The in is where the NMEA cable is connecting to. At the end of the run you need to have the terminator. Not sure what kind of issues will arise if you don't, but I know it needs to be there.
At first its a bit daunting all the connectors, cables, etc, but once you have done it its simple.
2. You want to be able to turn off the power to the NMEA network. It can still draw power when nothing is in use, example the GPS puck. Those things do not actually turn off with the GPS and if the NMEA network still has power, it will be drawing juice. I just ran my NMEA power supply straight to my master power switch at the dash. If you do not have one, you can add another switch dedicated for this.
3. There is a setting that matches the display brightness. I forget under which menu it is, but that is why you are seeing that.

Also, if you do get an Ethernet cable you can share waypoints between units. This will also allow you to share sonar which may or may not be something you are interested in. Just be advised that when you connect the Ethernet cable, by default "Network Sonar" is turned on and you will be viewing ONE of the units sonars. You have to turn this feature off if you don't want to share sonar, but you will still be able to share waypoints.
