- Purpose and compatibility This tool helps remove electrical connectors with locking tabs from common automotive components such as air mass meters (MAF sensors), fuel injectors, ignition coils, and other similar applications. - How to use (one-handed operation) 1) Use the hook at the end to release the locking tab. 2) Grasp the tab with the tip and squeeze to disengage. 3) Pull to disconnect the connector from the sensor. The auto-disconnect pliers are designed for convenient one-handed operation. - Build quality and materials The wire cutter features a high-quality housing that is wear-resistant, durable, and resistant to rust. It undergoes high-temperature forging and quenching to produce a sharp cutting edge, and an oxidation treatment enhances surface corrosion resistance to prevent rust and damage. - Ergonomics and handling Ergonomically shaped and non-slip, with a concave form and textured surface that provide a secure grip and room for handling with both hands. This design supports safe and straightforward disassembly and repair work. - Use scenarios - During engine service, quickly disconnect MAF sensor connectors without risking damage to the sensor or wiring. - Replacing or servicing fuel injectors requires safe, reliable removal of injector harness connectors. - General automotive electrical work involving locking-tab connectors on ignition coils or similar components in the engine bay.
