Product Description
Michigan Motorsports LS7 LS3 LS9 5-Wire MAF Sensor to 3-Wire LS1 Harness Adapter Connector with IAT
Fits Gen 3 LS1 3-Wire MAF Harnesses with External 2-Wire IAT Sensor | Adapts to LS3 LS7 LS9 5-Wire Card Style MAF Sensors
Upgrade your Gen 3 LS1 mass air flow setup with the Michigan Motorsports LS7 LS3 LS9 5-Wire MAF Sensor to 3-Wire LS1 Harness Adapter Connector with IAT. This adapter is designed for GM Gen 3 LS1 engines using the original 3-wire MAF sensor harness and external 2-wire intake air temperature sensor, commonly found on 1997-2002 LS1 Camaro and Corvette applications. It allows builders to adapt to the later LS3 card style 5-wire MAF sensor commonly found on 2010-2015 Camaro and Corvette applications. This is a clean solution for LS swaps, intake upgrades, MAF sensor conversions, and performance builds where you want to use a newer card style MAF sensor without cutting up the factory LS1 harness.
Key Features & Benefits
- LS1 Harness to LS3 Style MAF Adapter: Designed to adapt a Gen 3 LS1 3-wire mass air flow sensor harness with an external 2-wire IAT sensor to a later 5-wire card style MAF sensor. This makes it easier to run modern LS3, LS7, or LS9 style MAF sensor setups on earlier LS1 wiring.
- Built-In IAT Integration: This adapter supports the conversion from an external 2-wire intake air temperature sensor setup to the later 5-wire MAF configuration with integrated IAT functionality. This helps simplify wiring when upgrading to a card style MAF sensor used in many late model GM performance applications.
- No Cutting or Splicing Required: The adapter connector provides a cleaner way to complete the MAF conversion without permanently modifying the original LS1 engine harness. This keeps the installation more professional, serviceable, and easier to reverse if the setup changes later.
- Ideal for Intake & MAF Sensor Upgrades: Great for LS swaps, cold air intake changes, aftermarket intake systems, MAF sensor relocation, and performance builds using a newer LS3 card style MAF sensor. This adapter helps bridge the wiring gap between earlier Gen 3 LS harnesses and later 5-wire MAF sensors.
- Michigan Motorsports Conversion Solution: Built for LS customers who need a simple, reliable adapter for common LS1 to LS3/LS7/LS9 MAF conversions. It helps reduce wiring guesswork and gives builders a cleaner path to using a later MAF sensor on earlier LS-based vehicles.
