The light assembly should directly touch the bare metal of the vehicle chassis. The chassis is connected to the negative terminal of the battery; as such, the assembly touching the chassis provides proper grounding.

Connecting the wiring requires a wire connector and wire splicer. If there is not an existing license plate light assembly, consider contacting a trained electrician to help with the wiring.
