Attempting a flipper Fidelity install on my fun house. I cannot locate the single wire with a connector in the back box. I have a wire leading down to the cabinet speaker that is soldered with some shrink tubing over it from the previous owner. Can someone verify if this is where that connector should be so that I can solder it in place for this kit? If you've installed a FF kit in your funhouse, could you please let me know which wire has the single connector? I'm thinking it has to be the wire leading to the cab speaker, as there really aren't many connections from the soundboard but I don't want to fry the game. Thank you

Thank you. Yes, I found a drawn diagram on the funhouse thread and it looks like that is the wire in question. Appreciate your help!
