The $17 relay allows voltage to be sent to the wiring harness to operate the running lights on the trailer when you turn the headlights on your truck.
On my truck I have a class IV receiver hitch, the seven pin wiring connector for the trailer wiring, and two relays behind the battery in the relay box. I likely didn't need the more expensive relay, since I won't be using an electronic trailer brake, my boat weighs about 4,000 pounds.
