Plug and Pins Only - Delphi 2 Pin GM style Air temp (Grey)

Overview

Professional-grade Delphi 2-pin connector specifically designed for GM-style air temperature sensors in performance EFI applications. This OEM-specification grey connector ensures reliable sensor connections that won't fail under bonnet heat or vibration, critical for accurate air temp readings and proper fuel mapping.

Technical Specifications

• Part Number: HT-030410
• Connector Type: Delphi 2-pin sealed
• Application: GM-style air temperature sensors
• Housing Colour: Grey
• Temperature Rating: Automotive grade (-40°C to +125°C)
• Includes: Connector housing and terminal pins

Why You Need This

Air temperature sensor failures are often wiring-related, not sensor failures. Corroded connections, loose pins, or heat-damaged plastic housings cause intermittent readings that throw off your air/fuel ratios and timing maps. This is particularly common on LS swaps, turbo builds, and older Japanese imports where original connectors have deteriorated or been butchered by previous owners.

The grey Delphi connector is the OEM standard for GM air temp sensors found on LS engines, many aftermarket intake air temp sensors, and popular standalone sensor applications. Unlike cheap aftermarket alternatives, this uses proper Delphi housing with correctly-rated pins that maintain connection integrity through heat cycles and vibration. Essential for RB25/26 conversions using GM sensors, 2JZ-GTE builds, or any application where you're retrofitting proven GM temperature sensing.

ECU & System Compatibility

Compatible with all Haltech ECUs when used with appropriate GM-style air temperature sensors. Works perfectly with Elite 550/750/1000/1500/2000/2500, Nexus R3/R5, and Platinum series ECUs. The connector mates with most aftermarket intake air temperature sensors used in performance applications.
