Hello everyone, thank you for the replies, Mica, do you have any photos of the switches with the components? I did a good part of the wiring by looking at photos here on the site, if you could send some it would be a great help.
Another question is whether the connection of the selector switch is correct, it came with the wires cut as in the photo, I just replaced them with longer wires, if you could send photos it would also help me a lot, thank you!
