I have a space shuttle pinball that the sound keeps going off. I traced the problem to the sound connection to the power supply. If I push the connector in or even wiggle the wires the sound comes back on. So, I want to replace out that connector and punch down the wires in to a new connector. Sounds easy enough, but I am a newbie and really just need guidance on this. What is the part I need to buy (I know its a 15-pin - female), and what tool and where can I purchase it to punch down the wires into the connector. I have attached a stock photo (not of my board) to show you what I am talking about.
