Ideal for engine swaps, sensor conversions, custom wiring projects, and performance builds, this adapter gives you a simple plug-in solution for matching different GM MAP sensor connector styles.
Key Features & Benefits
- LS1 Harness to 1 Bar MAP Sensor Adapter: Designed to connect an LS1 MAP sensor harness to a compatible 1 Bar MAP sensor used on earlier GM applications. This helps simplify sensor wiring when mixing LS1 harnesses with LT1, LT4, TPI, or TBI-style MAP sensors.
- Plug-In Conversion Design: The female end plugs into the LS1 MAP harness and the male end plugs into the 1 Bar MAP sensor. This adapter-style setup helps reduce wiring work and keeps the installation cleaner than cutting and splicing connectors together.
- Great for Swaps & Custom Builds: Ideal for engine swaps, harness conversions, retrofits, and custom EFI projects where the harness and MAP sensor connector styles do not match. This is a practical solution for builders working with mixed GM engine and wiring combinations.
- Supports Proper MAP Sensor Communication: A secure MAP sensor connection is critical for accurate manifold pressure readings and proper ECU fueling calculations. Using the correct adapter helps maintain a dependable electrical connection for smoother engine operation.
- Wide GM Application Coverage: Designed around popular GM Camaro, Firebird, Caprice, Impala, Roadmaster, Fleetwood, TPI, TBI, LT1, LT4, and LS1 combinations. This makes it a useful adapter for both restoration-style repairs and performance-focused wiring conversions.
