Picked it up today.
It actually comes with a printed manual. My X9303 didn't even come with a printed manual.
The switch is wired to connect the signal and negative wires. It looks like you can just trim the futaba tab off the connector and plug a smart-fly pin/flag lead in. The pin/flag on my Fromeco Arizona Reg is wired different. Another option would be to use an extension and the bind plug. I prefer not to use a slide switch because I witnessed one vibrate off on a 33% H9 Edge.
