Wow, what a joke, took forever to dwnld 34 pages of your manual. Gigabyte needs a faster server.
2 pin Clear CMOS, no probs, forget the number "3" connector, it's useless to you, not needed at all in your situation.
Anyhow, with the jumper off, your mobo/CMOS is in "normal" mode, jumper on it clears.
Too easy. The switch is set up for a 3 pin mobo, so no matter how you look at it, in one position the switch is closed between the contacts labelled 1 and 2, in the other position it's open. Orientation of the connector on the pins does not matter, this is a simple switch, it is either OFF or ON, polarity is not an issue. I can assume which is which, but let's not do that, $350 assumptions are not all that bright.
Grab a multi-meter/ohm-meter, place a probe in each of the switch's connectors, as in one of the probes in "1" and the other in "2".
Set your meter to ohms/resistance.
It does not matter what the label on the switch says, when you have
ZERO resistance, the switch will be set to
Clear CMOS in reference to your mobo. Mark the switch as such, so you don't forget.
Move the switch to the other position, you should have
INFINITE resistance, that would be
NORMAL in reference to your mobo, mark the switch as such.
Move the switch to
NORMAL, as in the position you marked as "normal" on the switch. Connect it to the mobo. You're set to go.
When you need to clear the CMOS, shut down, turn off the PSU switch, push the power button on your computer(fans will probably spin briefly), disconnect the power cord from the PSU, move the switch to where you marked it as
CLEAR CMOS. Leave it there for whatever amount of time your manual suggests(probably 30 seconds or so), set the switch back to "normal", and you're done.
Piece of cake. This WILL work.
