Product Description
Michigan Motorsports MAF Adapter Harness LS3 LS7 with IAT Plug Series III to LT1 / LS1
Adapts LS3 / LS7 Harness to LT1 / LS1 Style MAF Setup | Includes IAT Sensor Plug for Series III Applications
Complete your MAF and IAT wiring setup with this MAF Adapter Harness for LS3 / LS7 harness applications using an LT1 / LS1 style MAF configuration. This adapter is designed for Series III cars that are changing to an LT1-style MAF setup, a common configuration for turbo builds and custom intake plumbing. Because this MAF style does not have an intake air temperature sensor built in, the harness includes an IAT sensor plug that allows you to install a Series II-style IAT sensor separately. This gives builders a cleaner wiring solution when relocating the IAT sensor and adapting the MAF connection for performance, swap, and custom forced-induction applications.
Key Features & Benefits
- LS3 / LS7 to LT1 / LS1 MAF Adapter: Designed to adapt an LS3 / LS7 style harness for use with an LT1 / LS1 style MAF setup. This is useful for Series III cars changing MAF configurations during performance upgrades, intake changes, or custom engine bay wiring.
- Built for Series III Conversion Setups: Commonly used on Series III applications switching to an LT1-style MAF, especially in turbo setups where the intake routing, sensor location, or MAF configuration is being changed from the factory layout.
- Includes IAT Sensor Plug: Since this MAF style does not have an IAT sensor built in, the harness includes a separate IAT plug so a Series II-style intake air temperature sensor can be installed in the preferred location.
- Supports Flexible IAT Placement: The IAT connection allows the intake air temperature sensor to be moved within the harness extension range, making it easier to place the sensor in a practical location for turbo piping, intake tubes, or custom air intake layouts.
- Cleaner Wiring for Custom Builds: This adapter helps avoid cutting, splicing, or piecing together mismatched wiring when changing MAF and IAT configurations. It is a clean solution for swaps, turbo builds, diagnostics, and custom engine management wiring setups.
