Description

The Putco H4 wiring harness is a heavy-duty upgrade for your vehicle's lighting system. It bypasses the factory headlight switch to pull power directly from the battery, which increases headlight output. The harness features durable 16-gauge wiring and heat-resistant connectors rated up to 480°F.
