Description

The MS3Pro LS PNP Alternator Extension Harness provides a 30-inch extension for your GM LSx alternator subharness. It’s the perfect solution when running Camaro, Firebird, GTO, or CTS-V accessory drive systems where the alternator is mounted farther from the main harness.

This extension also works with aftermarket brackets that relocate the alternator to a low-mount position or to the passenger side of the engine bay.

We’ve included all four wires in the harness, not just the power circuit. That means you can use this extension with our MS3Pro Plug and Play Harnesses

Built with high-quality automotive-grade wiring, this extension ensures signal integrity and reliability for your charging system, no matter the layout.

Key Features:

  • 30″ alternator harness extension

  • Fully populated with all 4 alternator control wires

  • Supports LS1, LS2, LS3, LS6, and other GM LS-family engines

  • Ideal for use with relocated alternator brackets or LS swaps
