Hello, I have made several arcade controllers. And they have all gone well, with very few problems. And I recently got a P360. And I can't figure something out. I am wiring the arcade controls to a playstation controller. And I look at the p360 and it has 4 prongs, one for each direction. But Im used to having to wire the main, and the ground (two wires for each direction). So how do I connect just one wire to the playstation pad?
