WHY USE A HARNESS PLUG KIT?
After certain factory components are removed or replaced, unused electrical connectors may be left exposed under the hood. Rather than leaving these connections open to the elements, a harness plug kit allows you to properly cap and protect the unused connectors while keeping the factory wiring harness intact.
It's a simple finishing touch that helps keep your wiring protected and your installation looking clean and complete.
