wiring up new horns, need help with relays

[pimpedout97x 4]

can someone finish this diagram for me?

keep in mind, i will have TWO sets of horns, and TWO relays. so i need to know how to hook up the one switch for both sets of horns, to both relays.

also, i just need one fuse for both power wires going to the relays right? what amperage should i get?

the horns are Hella Supertone 85115's.
