installing relays with the EZ wiring harness

i haven't wired it so far cuz i want to be 100% before cutting wires neither have i put power to the fuse block since i'm installing the harness with dash out. should i have my headlight power wire go to terminal 30 and 86 while my switch go to 85 but then where would terminal 87 hook to?

Or would my headlight power wire hook to the 87 terminal while my switch goes to the 85 and then i have a fused power wire go to 30 and 86?
