What This Harness Does

The Hall Effect sensor harness is the wiring cable that connects the left rear leveling sensor to the Ground Control 3.0 leveling system. When this harness fails from chafing, corrosion, rodent damage, or connector fatigue, symptoms typically include:

• Erratic sensor readings from the left rear position
• Auto-level cycle failing to complete or reporting sensor faults
• Intermittent leveling errors that come and go

⚠️ Left Rear Position Specific

This harness is engineered specifically for the left rear sensor position on Lippert Ground Control 3.0 5th wheel systems. Verify the position of your failed harness before ordering.

For Ground Control 3.0 5th Wheel Systems

Engineered specifically for the Lippert Ground Control 3.0 5th wheel platform. NOT compatible with Ground Control 2.0, Ground Control TT, or Level-Up systems.

Right Rear Position Also Available
