FV270 dash ground block?

Thought I saw a post where someone said there should be a ground block behind the dash?

I've looked and cannot find it.. my goal is to add an accessory switch. 

Seems straightforward to add power to my switch:



But having problem locating where I should run the ground wire to? I couldn't locate a ground block...This is all I could find where all the other grounds go to:


Does this mean I'll need to run a ground directly to the battery?

    I’ve been behind the “dashboard” of my FV270 more times than I’d like to admit... don’t remember ever seeing a ground block. I always tied into an existing ground wire... just remember that the salt water environment makes “shotty” connections fail much quicker than behind the dash of your car.... solder and Shrinkwrap!

    Why not add in a ground block and clean up the grounds?  Single ground wire running to battery?

    I have a junction block and three network junctions mounted to a piece of Starboard that is screwed to the back wall.  It helped me organize wires, and it also prevents these components from getting bumped around.  It still looks like a rat's nest, but it's much better than it was.

    Originally, the junction block was just hanging loose inside the helm, wrapped in electrical tape.  Maybe yours is like that.

    Why do you need to add a negative to a switch? Hot leg and switched leg. If its for a light indicator just tap the negative off the switch next to it........ Just say'n

    @LaRea is that a NMEA2000 hub?

    It's SeaTalkNG, which is Raymarine's version of N2k.

    Thanks everyone. Looks like I'll be adding a ground block and running that back to the battery. Was just hoping I was overlooking some dark corner.

    @raybo3 sorry, I didn't mean a negative for the switch but for the accessories that will be connected to that switch. 
    @LaRea that looks much cleaner than what I see behind my panels!
