MS3Pro LS Plug and Play Harness Alternator Lead Extension Printed Label Wire Gauge Base30 extension for GM LSx alternator subharness. Our harness will require this if used with Camaro, Firebird, GTO, or CTS V accessory drives. You can also use this with aftermarket brackets that move the alternator to a low mount position or relocate it to the passenger side. Weve populated all four wires, so this extension isnt limited to just our harness. You can use it with OEM harnesses or wiring from other sources, and use it with any ECU.
