The power supply is a 12V golf cart battery hooked up to a battery tender. I'm sure that's way more power than a cluster needs but my dad fixes golf carts so it was free.
As for the wiring, a few years back, I bought a mostly complete body/engine harness from someone on Vortex. I've used many of the wires and connectors for various car projects including this bench setup. I've got power/K/CAN wiring going to the OBD port, the blue/green cluster connectors, an ECU connector, an airbag connector, CCM connectors and both single and double DIN radio connectors. It's super messy and wastes a whole workbench but it's great for cluster programming and more recently reverse engineering how to communicate with the various car modules. Behind the laptop on the left is a Saleae 8-channel logic analyzer. I can connect it to either the K-line or serial port on the back of the laptop to spy on what is being sent over the wire to the cluster. It's plugged into a second laptop (not shown).
