I am at a loss also. My guess would be that the harness is setup to go to the battery directly for the power to the headlights. The other wires and a relay would included a ground wire (black) and then a connection that would plug into the original headlight harness, so that when you turn on the headlights inside the truck the power from that circuit would actuate the relay and turn on the new lights. The harness is probably wired so that it is simple to connect to the plugs that are already in the truck. My guess is that the 3 prong connector is for a standard headlight plug that is up by the radiator support.
