The GRACO 131378 is a wiring harness designed for use with the speed potentiometer (speed pot) in GRACO RoadPak line striping systems. Its primary function is to provide reliable electrical connectivity between the speed control potentiometer and the system controller, ensuring accurate speed adjustment and system operation. The material is not specified, but typical harnesses are constructed from insulated copper wire with durable connectors.

Key Features:

• Wiring harness
• Insulated wire with connectors (assumed, not explicitly stated)
• GRACO RoadPak line striping systems
• Designed for reliable electrical connectivity
• Supports accurate speed control via potentiometer
• Engineered for integration with GRACO RoadPak controllers

Applications:
Used in GRACO RoadPak line striping systems for connecting the speed potentiometer to the system controller, enabling precise speed adjustment during road marking operations.

Installation Notes:

• Using a genuine GRACO harness ensures compatibility, reliability, and optimal performance of the RoadPak system.
