The point of a relay is to be able to control higher amperage loads using switches that are not cable of passing that current.
So a relay generally has an input and output for the load, ground connection, and a separate connection for the control which generally goes to a switch.
The control circuit passes little to no current so 18-20 AWG is a pretty standard wiring size for those applications.
Chances are you are going to end up with some bosch style relays. Here is a wiring diagram / example:
