I have 4 ways and 8 ways in my current control panel, and yes they're wired together. Works fine and no need to waste 4 more inputs.... however I'm planning on rebuilding the CP soon and just using the mag-stik pluses from ultimarc since they're switchable from the top and I can just get rid of 2 joysticks. Having 4 joysticks on a 2-player cab worked ok for my first time out but it's really a waste of space...
