Haltech MAP Sensor Connector - GM - 1 Bar - Plug & Pins Only

Overview

Professional-grade connector designed specifically for GM 1-bar MAP sensors in Haltech EFI conversions. This genuine Haltech connector ensures reliable manifold absolute pressure readings — critical for accurate fuel and ignition mapping across naturally aspirated and low-boost applications. Essential for clean, factory-standard connections in LS swaps, GM truck builds, and performance EFI conversions.

Technical Specifications

• Part Number: HT-010101
• Application: GM 1-bar MAP sensors
• Pressure Range: 0-1 bar absolute (14.7 PSI)
• Configuration: Plug and pins only
• Connector Type: GM OEM specification

Why You Need This

MAP sensor reliability is non-negotiable in any performance build. The manifold absolute pressure reading drives your ECU's load calculation — get this wrong with a dodgy connection or incorrect sensor range, and you're looking at lean conditions, knock, and potential engine damage. GM's 1-bar MAP sensors are perfect for naturally aspirated builds and mild boost applications up to about 14 PSI, but only if you connect them properly.

We see too many builds using generic automotive connectors that corrode, create voltage drop, or simply don't fit properly. This genuine Haltech connector matches GM's OEM specification exactly, ensuring the clean 0-5V signal your ECU expects. Particularly crucial in LS swap applications where you're often relocating the MAP sensor or extending harnesses — any resistance in the signal path affects your air/fuel accuracy across the entire load range.

ECU & System Compatibility

Compatible with all Haltech ECUs when using GM 1-bar MAP sensors — Elite 550, 750, 1000, 1500, 2000, and 2500 series, plus Nexus R3 and R5 platforms. Ideal for builds where the stock GM sensor range matches your application requirements. Contact our team to confirm sensor selection for your specific boost targets and ECU configuration.

What's in the Box

• GM MAP sensor connector plug
• Terminal pins
• Sealing components

Complete Your Build

Most customers building LS-swapped vehicles or GM EFI conversions also add proper engine harness connectors and sensors to match. If you're running higher boost levels, consider upgrading to a 2-bar or 3-bar MAP sensor with the corresponding Haltech connector. Our technical team keeps GM sensor applications and Haltech ECU compatibility charts on hand — contact us before ordering to ensure you're selecting the right pressure range for your build.
