Hmmmm....yes, that is probably the one connector that if you can just find where to plug it in your surf wave would tune itself to perfection, giving you the ultimate wave every time without any hassles or extra weight! That is where my mind would immediately go! I will have to look around under there on my 21 Makai and see if I notice an extra plug like that. I do know wiring harnesses often have unused plugs. I have the flow 3 as well.
