LMMF 00+ 96–99 3100 / 3400 Injector Harness Adapter
Quick solution for mixing 3100 / 3400 wiring generations.
The LMMF 00+ to 96–99 3100 / 3400 Injector Harness Adapter provides a simple plug-and-play solution. This allows you to run a 2000–2005 style 3100/3400 engine harness on a 1996–1999 style engine.
Normally, swapping injector harnesses requires removing the intake manifold, which adds unnecessary time and frustration during a build. This adapter eliminates that step entirely, allowing you to connect the newer harness directly to the earlier engine setup.
It’s the perfect solution for engine swaps, simplified wiring harness builds, and derby setups. Builders want the flexibility of using a 2000–2005 harness without tearing the engine apart.

Designed for quick installation with no cutting, splicing, or complicated wiring required.
2. Cross-Generation Compatibility
Allows a 2000–2005 style 3100 / 3400 harness to work with 1996–1999 engines.
3. No Intake Removal Required
Avoid the hassle of removing the intake manifold just to swap injector harnesses.
4. Saves Time During Swaps and Conversions
Perfect for builders who want a fast, efficient solution when converting harness setups.
5. Clean and Reliable Connection
Provides a simple and dependable wiring solution for engine swaps and simplified builds.
Built for Simplified Engine Wiring
Whether you’re upgrading to a newer harness, building a simplified ECM setup, or working through a derby engine swap, this adapter provides an easy way to connect the pieces. You can do this without unnecessary work.
