It looks to be 12 wires that need to be disconnected before the cluster can come out. I really wish there was a single connector, or maybe even two. Maybe a future project...
Here's the back of the cluster in case you were curious.
And here's the cluster back where it belongs. All the gauges are AutoMeter behind the stock bezel. The gauges sit in a plastic gauge pod that's made for just this purpose. Unfortunately the speedo sits a little too high and is not adjustable. A lot of the online reviews of these pods state the same problem. Oh well.
