Quoted from Nevus:2nd game, Stranger Things Premium.
The back box board did not have an empty cable slot due to the topper. I used the only open one on the playfield, lower left close to apron.
Here are a few more photos of the steps to better clarify the process. This time about 20min.
The coin door kit is really nice and looks like it came from the factory.
The metal apron on the Stranger Things Premium has a mount for the QR code reader under the right-side card. I'm curious why you decided not to use that.
