I did a custom dash not that long back and its still not complete. I know if each wire is fed from the next it will drain the 12v power and be lower and lower. I have 5 guages here , the volt meter is on its own and the other 4 have indipendent wires for the lights run all the way down until the last foot or so, then there spliced into a single wire for the power at the fuse box. They are still really dull and not getting 12v each, they seem to be sharing it. Whats the best way to finish it?
