Cluster light fuse keeps blowing
Here us the connector. Black wire looks to be going to the 2 orange. And nothing on the outer black wires.

Yep, you can see it right there. Every wire is color to color , one connector to the other, except orange is going to a black. Look at it, pink to pink, and next port is orange to black.
This switch to cars harness connector had extra ports so they used them for the shift indicator lamp, ignition switch lighting, key buzzer, whatever, instead of adding a separate connector for the different builds.
You have 2 orange wires in the cars harness connector. One of them to feed the shift indicator. The other is a branch to something else (which only saved them wire length) and connectors.
Aftermarket wants to provide only a "one size fits all switch". If you're not color blind you can finger out.
I honestly dont know if that added black wire was a hot branch out to a reverse lamp in a different model, or a ground for something, but either/or, it will blow the illumination fuse in our a-body. We've already seen this about a dozen times. Orange goes to orange or it don't go to anything. Take the 2 orange wires away from the black wire, one more fuse, happy moparing.
