-VE (GND) wiring

[Solent Bombard]

I'm at the point of now reinstalling my wiring setup and and undoing the bodged mess that was in there before.

I have now realised there was very dodgy -VE setup before and mostly consisted of lots of wires twisted together to join up all the gauges and the wire directly to the battery.

I'm going to install a busbar (bluesea) to tidy up and route my -VE properly.

Should I though connect up each gauge to the busbar individually to have a GND each or is it ok to sort of daisy chain all the gauges onto one wire seeing as it's pretty low voltage anyway.

And then Separately connect my lights,vhf and plotter to the busbar

How many -ve wires are we talking about?

[Solent Bombard]

5 gauges tachometer,speed,trim,fuel,temperature for now

And then

Chartplotter

Vhf

And maybe some other bits in the future

I was thinking on going for this now seeing as it has +VE and -VE and 12 terminals so should be pretty much future proof for my boat

I've got one of those on the Ballistic and a 6 way on the Searider.
I wouldn't be too worried about piggybacking gauge negatives, but give everything else it's own fuse and -ve.
