here is a quick read on the relays and how they are wired up for different applications

you can also find items like this locally most likely

you will likely want to wire a relay into the circuit for high draw items that are switched on for extended periods, like headlights, heater fan, rad cooling fan, if you have one, electric wipers, driving lights etc, and also some intermittent high draw items like the horn. it would be a great time to install a daytime running light relay if you plan on having that safety item. if so, you can wire the tail lights in the circuit so you don't drive around in the dusk with no tail lights because you forgot to turn them on.
