Haltech Delphi 3 Pin Pressure Sensor Connector Plug & Pins - HT-030412

The Haltech Delphi 3 Pin Pressure Sensor Connector Plug & Pins (HT-030412) is the correct mating connector for Haltech's range of Delphi-style 3-pin pressure sensors — including sensors used for oil pressure, fuel pressure, boost pressure, and other fluid monitoring applications in engine management builds. Whether you're repairing a damaged connector on an existing harness or building a custom wiring loom from scratch, this plug-and-pins kit ensures a proper, factory-style termination that is fully compatible with Haltech's Delphi sensor lineup.

Key Features & Benefits

• Correct OEM-Style Delphi Connector: Designed specifically to mate with Haltech's Delphi 3-pin pressure sensors, eliminating guesswork and ensuring a secure, reliable connection in demanding engine bay environments.
• Plug & Pins Included: Comes as a complete connector assembly — both the plug housing and the required pins — so you have everything needed to terminate your wiring in one kit.
• Supports Multiple Pressure Sensor Applications: Compatible with Haltech pressure sensors such as the 2000 PSI unit (HT-010908), making this connector useful across a wide variety of motorsport and performance builds where fluid pressure monitoring is required.
• Genuine Haltech Part: Sourced directly from Haltech (MPN: HT-030412, UPC: 9356450002813), so connector tolerances and pin fitment match exactly what the sensors are designed to receive.
• Clean Custom Harness Builds: Ideal for fabricators and tuners building from-scratch engine harnesses around Haltech ECUs who want correct, tidy connector terminations rather than improvised solutions.
• Connector Repair & Replacement: A cost-effective way to repair or replace a damaged Delphi pressure sensor connector without replacing the entire harness or sensor assembly.

Frequently Asked Questions

Q: What sensors does this connector work with?
A: The HT-030412 is the mating connector for Haltech's Delphi 3-pin pressure sensors. It is confirmed to be used with sensors such as the Haltech 2000 PSI Pressure Sensor (HT-010908). If you have another Haltech pressure sensor that uses a Delphi 3-pin connector, this is the correct plug-and-pins kit to pair with it.

Q: Does this come with both the plug housing and the pins?
A: Yes. The HT-030412 is described as a "Plug and Pins Only" kit, meaning it includes the connector housing and the associated pins needed to complete the termination. No additional connector hardware should be required.

Q: Is this product vehicle-specific or universal?
A: This connector is application-specific to Haltech's Delphi 3-pin pressure sensors rather than being tied to a particular vehicle make, model, or year. It's used in custom and motorsport harness builds wherever a Haltech Delphi-style pressure sensor is wired in.

Q: How do I order and when will it ship?
A: The HT-030412 is a regularly stocked product at ThreePiece.us. Add it to your cart and complete checkout — free shipping is included on all orders. Financing through Affirm is available at checkout if needed. For any order or fitment questions, reach our team at 813-535-5801.
