LS Fuel Injection Wiring Adapter

The CARROFIX 558-416 adapter harness connects an existing LS fuel injection wiring harness using an LS1/2 style MAP sensor connector to an LS3-style MAP sensor. It serves automotive technicians and enthusiasts modifying LS engine management systems or installing LS Hi-Ram intakes that require the LS3 MAP sensor interface.

LS1/2 to LS3 MAP Connector Constraint

This harness only bridges the specific difference between the LS1/2 MAP sensor plug and the LS3 MAP sensor plug. It cannot adapt other sensor types, injector connectors, or throttle body interfaces present on the engine harness. Installers must verify that the remaining harness connectors match their specific ECU and engine configuration before use.

Questions about this item

Should I choose the 558-416 adapter if my LS harness uses an LS1/2 MAP sensor connector?

Yes, the 558-416 is built to adapt any LS harness with an LS1/2 MAP sensor connection to an LS3-style MAP sensor, so it matches that requirement directly.

What does the 558-416 adapter actually do once it is installed in the engine bay?

It connects the existing LS1/2 MAP sensor wiring to an LS3 MAP sensor, allowing the ECU to read the LS3 sensor signal without rewiring the main harness.
