adding AIS looking for install info

[nzfisher]

So along with new radar and navigation I am installing AIS. Today for the first time I looked behind the switchboard control panel and saw that anything I do is not going to be fun. Where have folks who have installed AIS pulled power for the negative leg 12 volts? I am going to avoid working in the spaghetti closet at all costs. There is a blank spot on the fuse block in the fold down for 12 volt positive but where do you put the negative lead in the same area?

I just installed AIS on my 2013 R-27. The fold-out fuse/terminal block has lots of yellow wires connected to a negative bus at the hinge end.

Feel a little foolish- wasn't looking for yellow. Thanks
