If you installed the Curt T-Connector Vehicle Wiring Harness # C56181 on your 2017 Chevy Traverse and none of the trailer lights are working when hooked up then there are a couple of things you will want to take a look at.

The first thing I recommend doing is simply making sure the white ground wire coming from the harness is securely attached. This needs to be connected to a clean bare metal surface on the vehicle's frame to ensure a proper ground.

If the ground looks good you will next want to make sure you have the hot lead properly ran to and attached to the positive post of the Traverse's battery. This powered converter is needed both to combine the separate light circuits on the Traverse to be compatible with a trailer's wiring and also provide sufficient power to the lights.

If this doesn't resolve the issue please let me know and we can continue to troubleshoot.
