Wiring & Communication

Whether you’re pulling one trailer or three, from the battery to the last stop tail turn light, you need a system that’s designed to work together flawlessly to get power and control throughout the vehicle. Grote’s Harnesses, Nose Boxes, Power Cords, and Pigtails seal out corrosive chemicals, protect against vibration, and ice build up to ensure the right amount of signal and power gets to every light and safety component.

Grote pigtails are designed to maintain an unimpaired plug to lamp connection. We offer multiple pigtails, including versions for clearance/marker, sentry lamp, and stop/tail/turn lamps. Several also include our patented double seal technology to guarantee waterproof protection.
