If I get 5 standalone gauges, is there a way to neatly splice the wires into the 12v , ground wires etc.. for all of them together. What I mean is can I connect all the gauge wires of the same type to some sort of connector before splicing into the car's wiring? I don't really know electronics so I want to make wiring as simple as possible, without buying something like the Defi Link system. TIA

 

you can ground all the wires to each others cases 1 by 1 to keep it clean that way only 1 gorund wire has to be used and you can kinda do that with power...just use your amigination to keep it clean.
