The TE Connectivity connectors 174357-2 and 174359-2 are a matching pair of 3-position, single-row waterproof automotive connectors from the reputable AMP Econoseal J Series Mark II family. They are specifically engineered to withstand harsh environmental conditions inside engine bays and vehicle chassis.

• Stable Insulation Resistance: The PBT housing material guarantees a minimum insulation resistance of 100 Megohms (MΩ) between adjacent pins, ensuring no current leakage or "cross-talk" even in high-humidity environments.
• Visual Confirmation Mechanism: The internal Terminal Position Assurance (TPA) plates are color-coded (usually bright yellow or red against the black housing) for instant visual confirmation that the secondary lock is fully engaged and terminals are perfectly secured.
• Damage-Free Terminal Release: Fully field-serviceable design allows removal of individual pins for repinning or diagnostic testing without destroying the housing using standard tools.
• Optimized Insertion Force: Engineered internal terminal tracks provide low mechanical insertion force, reducing worker fatigue and preventing wire buckling during harness manufacturing.
