The Genie 99778GT 4-Wire Cable Squeeze Connector is a genuine OEM connector built for Genie S series telescopic boom lifts and Z series articulating boom lifts. As a factory-sourced component, it matches the original specification exactly, ensuring a correct, secure connection every time. This connector is confirmed to fit a wide range of S and SX series telescopic booms — including the S-40, S-60 XC, S-65 TRAX, S-80, S-85 XC, SX-105 XC, SX-135 XC, and SX-180 — as well as select Z series articulating booms such as the Z-60/34, Z-80/60, and ZX-135/70. Cross-reference part number 99778GT against your machine's parts manual before ordering to confirm it is the correct connector for your unit.
Key Features
- Genuine OEM Construction — Sourced directly from Genie, this connector is manufactured to the original dimensional and contact specifications, so pin alignment and retention force match what the machine was built with.
- Exact 4-Wire Configuration — The four-wire squeeze connector format matches the original harness layout, allowing the connector to seat and lock into place without modification to the wiring or housing.
- Broad Boom Lift Coverage — Fits Genie S and SX series telescopic booms and Z series articulating booms across multiple model years and variants, from compact S-40 models through the large-platform SX-180.
- Maintains Electrical Continuity — A worn or damaged squeeze connector can introduce resistance, cause intermittent signal loss, or result in a failed connection altogether; replacing it with the correct OEM part restores a consistent, low-resistance electrical path.
- Operational Safety on Aerial Platforms — Electrical connectors on boom lifts carry signals critical to platform controls and machine functions. A sound, properly seated connector is essential to predictable machine response at height.
A cable squeeze connector joins sections of a multi-wire harness by compressing and locking two mating halves together around the conductors, securing both the mechanical connection and the electrical continuity of each wire. On boom lifts, these connectors are used throughout the machine's wiring circuits to link control signals between the platform, the chassis, and the boom structure. When a connector degrades — through corrosion, cracking, or a weakened squeeze mechanism — individual wires can lose contact intermittently or completely, leading to erratic controls or machine faults. Replacing a failed connector with the correct OEM part restores the integrity of the connection and keeps the circuit functioning as designed.
