What's with the ring terminals? Won't need them. Wire right into the power drop. I hardly ever see it on these forums, but I am a dedicated solder man. I see connectors used online by people, and I hate those things. That is what the audio folks use because it saves time and they don't care about the customer. Some on here also are diehards with connectors. Those things can come loose and/or corrosion can have access. It may also look better than solder and tape, but I don't believe in those things. Do the gauges glow or anything? I would go digital, but you already bought the stuff.
