It features a factory-molded Turtleback II plug on one end that connects to specific Grote stop/tail/turn lamps (4680, 4684, 4686, and 4687 series), and a slim-line .180" male bullet/ring terminal on the other for chassis grounding. You typically use this pigtail when replacing or repairing trailer lights to ensure a sealed, weather-resistant connection that's compatible with Grote's ULTRA-BLUE-SEAL wiring system. This 2-wire, 14-gauge design helps prevent corrosion and electrical failures in harsh on-road and off-road environments.
