Bench testing a gauge cluster

Do you have an extra set of wiring connectors for the cluster?
If so, you can connect all the black wires together to ground & the red/black wires together to power.
I honestly don't know which pins in the connectors go to what wire, but next time I've got mine out I'll see if I can trace down the connections on the cluster.
In the meantime, here's the only good pic I have of the back of one of my old clusters where I marked the polarity for the backlighting:
I'd be willing to bet $0.25 that if you connect power & ground to one of those socket connections, it would feed power to the rest of them or at least the rest on that circuit.

If you're gonna be using led's to test in the cluster, a plain old 9v battery from a smoke detector should work.
If you're gonna be using incandescent bulbs, I'd suggest getting a 12v dc wall wart power adapter from some old electronic device & using that for your power. As long as it has 1000mA or 1A of DC output, it should be good even when using incandescent bulbs.
It will work the same for led's, just need to check the polarity on the wires. I've made & used several of them over the years. They're cheap & handy to use & if it happens to fly across the shop & smash into a million pieces, I'm only out a few bucks
I'm way behind on getting more **** inserts made up, but I may have one set done
