Wiring multiple gauges correctly?

[LaunchHard]

I currently have 4 gauges wired in 3 in the center and one on the pillar, but I am adding a wideband and would like to rewire the gauges for more efficiency. The center 3 have 2 powers and two grounds, one for the gauges/sensors and one for the lights. The lights are wired to the dimmer, but they are drawing too much power because the lights are not asvright as they should be.

What is the best way to send power to the gauges to keep them from losing their brightness? And what is the best way to wire all of them in?

Relay(s) and a decent power/ground wire.

I just put 2 guages in my vent and the easyiest way to wire them is off the cigaret lighter and then tap into the lines comming from one of the cig lighters lights since its on a dimmer for light bulbs then throw a fuse in line for the 12v+ and your all set. I know you probably already figured it out but someone else might be interested.

Are you wiring the lights in series or parallel?
