Wiring Harness Pigtails

If you aren't going to use one of our LED light bar wiring harnesses, then you may want these pigtails to splice into your custom wiring setup. Though many drivers are interested in adding LED light bars to their vehicle, some hesitate to do so because they worry that their installation might be difficult. The reality, however, is that there's an easy way for both your existing lights and any additional ones to be connected under the same terminal. All you need is fifteen minutes, a few tools, and a set of pigtail connectors. A pigtail connector is nothing more than an electrical wire used to connect two or more wires. Take a look at the kits and parts below to determine which one best suits your wiring needs. None of our pigtail connectors cost more than eight dollars, and the tools required to make use of them are common and inexpensive. With a little effort, you can enjoy the accomplishment of having worked on your vehicle with your own hands and the satisfaction of saving money.
