2-Pin Automotive Sensor Connector – Intake Pressure Sensor & Headlamp Plug for Automotive Wiring Harness Repair

A 2-pin automotive connector plug used for intake manifold pressure sensor (MAP sensor) connections and small lighting applications including headlamp sub-connectors, position light connectors, and indicator light connections. The 2-pin configuration is the most common in automotive applications — used for any simple power/ground or signal/ground sensor and lighting connection throughout the vehicle. This connector is suitable for multiple applications where a compact 2-pin waterproof connection is required.

Key Specifications

• Pin Count: 2 pins
• IP Rating: IP67
• Housing Material: PA66 nylon, flame retardant
• Operating Temperature: -40°C to +125°C
• Application: Intake pressure sensors, headlamp sub-connectors, position lights, and general 2-pin automotive sensor connections

Common Applications for 2-Pin Sensor Connectors

• MAP sensor (Manifold Absolute Pressure): 2-wire MAP sensors use a 2-pin connector carrying signal output and ground. 3-wire MAP sensors (with 5V supply) use a 3-pin connector — verify the sensor pin count before ordering.
• Headlamp sub-connectors: Small 2-pin connectors for position light, DRL, and indicator sub-circuits within the headlamp assembly
• Coolant level sensor: 2-pin connector for coolant level switch (open/closed signal + ground)
• Oil pressure switch: 2-pin connector for oil pressure warning switch (signal + ground)
• Brake fluid level sensor: 2-pin connector for brake fluid level switch

Frequently Asked Questions

How do I identify the correct 2-pin connector for my sensor?

Identify the connector by: (1) the connector housing part number molded into the housing; (2) the connector dimensions and locking mechanism; (3) the contact pitch (distance between the two contact centers). Cross-reference the housing part number with the vehicle’s parts catalog to verify the correct replacement. For MAP sensors, also verify the contact pitch — different MAP sensor connectors use different pitches (0.64mm, 1.5mm, 2.8mm).

What contacts are compatible with this connector?

Contact compatibility depends on the specific connector series. Identify the contact size by measuring the contact cavity diameter in the housing, or cross-reference the housing part number with the manufacturer’s catalog. Order the correct contact size for your application.

Can I use this connector for both sensor and lighting applications?

Yes, if the connector housing and contact pitch match the original connector. The 2-pin configuration is universal for simple 2-wire connections — the same housing can be used for sensor signal/ground connections and lighting positive/negative connections, provided the contact pitch and locking mechanism match the mating connector.

Typical Applications

• MAP sensor repair: Replacing damaged intake pressure sensor connector housings
• Headlamp repair: Replacing damaged headlamp sub-connector housings
• Sensor wiring: General 2-pin sensor connector replacement
• Automotive workshops: Workshop stock for common 2-pin connector repairs
