I've got them
middle connecting strap - under seat
two other connecting strap- over seat
other straps I did one on each side to the pillion footpegs and the ones at the back I joined to each other.
My gf didn't notice any difference with the seat straps on or off because of the trousers she was wearing
Hope that helps...
Although I've just noticed it's for an FZ6, I'm on an FZS1000, but I would say it's all the same
except watch out for your underseat exhausts
