The Genie 99655GT is a genuine OEM Up Limit Switch Harness designed for GS-3384, GS-3390, GS-4390, and GS-5390 scissor lifts. As a factory-sourced component, this harness meets the original electrical specifications Genie engineers built into these machines — no guesswork on compatibility. Cross-reference part number 99655GT against your parts manual to confirm fitment before ordering. When the existing harness becomes damaged, corroded, or fails to signal correctly, this direct replacement restores proper communication between the up limit switch and the machine's control system.
Key Features
- Genuine OEM Electrical Integrity — Manufactured to the original wiring and connector specifications, ensuring the harness carries the correct signal output for the up limit switch circuit without resistance variations that can cause false readings.
- Direct Connector Match — Terminals, connector housings, and wire routing match the original harness layout, allowing straightforward installation without splicing or adapter fittings.
- Confirmed Fitment for Large-Frame GS Scissor Lifts — Fits the GS-3384, GS-3390, GS-4390, and GS-5390, covering Genie's heavy-duty rough-terrain and high-capacity scissor lift models.
- Restores Accurate Height-Limit Detection — A functioning harness ensures the up limit switch can reliably signal the control system when the platform reaches maximum elevation, keeping machine response accurate and predictable.
- Critical Safety Circuit Component — The up limit switch harness is part of the platform travel-limit system on aerial work platforms. A damaged or open-circuit harness can prevent proper machine shut-off at maximum height, making prompt replacement essential for safe operation.
The up limit switch harness is the wiring connection that links the up limit switch to the scissor lift's control system. When the platform reaches its maximum raised position, the up limit switch sends an electrical signal through this harness to cut power to the lift function and prevent over-travel. If the harness develops a break, corroded terminal, or damaged connector, that signal may not reach the controller — causing the machine to behave unpredictably at full height or trigger fault codes that take the unit out of service. Replacing a worn harness with the correct OEM part restores the integrity of this circuit and ensures the limit switch can do its job reliably.
