Link Terminated Engine Harness GM LS GEN3/4

Link's Terminated LS Engine Harness is a custom-built solution designed to connect either Link's StormX or XtremeX ECU to Gen 3 LS1/LS6 or Gen 4 LS2/LS3/LS7* engines. Whether you're powering a stock application, completing an engine swap, or building a high-end race car, it provides a clean and reliable foundation for your engine-management system.

The LS Harness includes connections for everything you need, including injectors, ignition coils, drive-by-wire throttle control, and CAN Lambda sensors, plus twelve spare connections for functions unique to your build.

Each harness uses Link's easy-to-work-with AVSS automotive wire and Link's standard wiring colors.

Before shipping, every harness undergoes comprehensive testing for correct pinout, shorts, splice resistance, insulation resistance, and more before being shipped to you.

LinkECU's Terminated LS Engine Harness uses a single, versatile base loom that can be tailored to your specific LS engine and application with a range of Link accessories.

Models Supported

Gen 3 LS1/LS6

Gen 4 LS2/LS3/LS7*

Warnings

*Notes for use with Gen 4 Engines

A cam sensor harness extension will be needed to accommodate the Gen 4 LS front mounted cam sensor.

A small modification is required to the crank sensor connector. See "crank connector" section in installation manual for details.

Injector Connector Adapters to USCar connector will be required for most Gen 4 Engines. Check your injector connector to confirm. Use Link PN 101-0287.

To support Gen 4 factory knock sensors you will require the Link LS Gen 4 Knock Adapter Loom (PN 101-0306).

To support the factory Gen 4 MAP sensor you will require a Link LS Map Adapter Loom plus a Gen 3 to Gen 4 MAP sensor extension harness (alternatively you can use a Link MAP sensor which is directly supported by the harness).

If you require a fuse box and relay, please purchase 101-0310 in addition.
