You will want to check the wiring connections and make sure the ground wire is secure on your 2012 Honda Civic. You will need to check each of the pins in the connectors on the vehicle side of the connectors to make sure they have current using a circuit tester like part # PTW2993. I have attached a helpful article that shows how to troubleshoot 4 and 5-way wiring installations.

Since you said all the lights work but the headlights are you referring to the vehicle turn and brake lights or the lights on a trailer. It sounds like there may be an issue with the vehicle wiring and not with the wiring harness.

When working with electrical connectors I recommend using dielectric grease like part # 11755. This keeps dirt and moisture out of the connections and helps prevent corrosion.
