While removing SAS (finally!) I've stumbled upon a loose connector happily hanging out above the radiator. Can anyone shed some light on what that is? I am aware of at least one that should be unconnected to anything (the tripmeter remote), but I think that one has a white connector with four wires, and this one looks like something important. And yes, I actually unscrewed the radiator. That, and together with loosening the oil tank gave me enough wiggle room to reach the right-side plate without taking the airbox out, so success there.
