You will know the pins are correct when you assemble them back in with the key in the lock and the cylinder will turn.
Go one hole at a time trial and error....when the key will turn go to the next hole.
I would rather use the EMGO switch I referred to in the other thread (#41-37600) than the one you link here. It is rated for 25 amps, and doesn't have open terminals which might ground out on the headlight.
