First, take out the battery.
then using the 13mm, take off the nose bolt
and the 4 inner bolts underneath the seat.
Remove the old seat, and if the new seat does not have a nose bolt, transfer over the one from the old seat with the flange facing the frame.
Put in the new seat nose-first, sometimes it helps to hand tighten on the nut to the nose before guiding the back pegs into the frame holes.
Give the back end a seat a little pop with your palm if it needs some assistance.
We only reinstall the back 2 of the 4 nuts, as combined with the nose nut is more than sufficient to keep the seat in place.
