Link Terminated LS Engine Harness, Gen 3 / Gen 4 LS1, LS6, LS2, LS3, LS7 (101-0300)

Link's Terminated LS Engine Harness is a custom-built base loom that connects a G4X StormX or XtremeX ECU to Gen 3 LS1/LS6 and Gen 4 LS2/LS3/LS7 engines. It carries the connections for injectors, ignition coils, drive-by-wire throttle control and CAN Lambda sensors, plus twelve spare connections for functions unique to your build, and one harness is tailored to your engine with Link's adapter looms. The ECU, a fuse and relay box and the throttle adapter are sold separately.

Highlights

• Fits Gen 3 LS1/LS6 and Gen 4 LS2/LS3/LS7 engines (Gen 4 needs the extra parts listed below)
• Cable throttle bodies use the LS Stepper Adapter (101-0301); drive-by-wire throttle bodies use the LS DBW Adapter (101-0304)
• EV1/JPT injector connectors plug directly into common LS1 injectors
• Supports the factory 7-pin coil harness connector and the factory F Body alternator (ACDelco 335-1075)
• Powered DTM4 CAN connector, compatible with Link CAN accessories and cables
• Supports Link MAP sensors directly; the LS MAP Adapter retains the factory Gen 3 MAP sensor
• Built with Link's AVSS automotive wire in Link's standard wiring colours
• Every harness is tested for correct pinout, shorts, splice resistance, insulation resistance and more before it ships

Notes for Gen 4 engines

• A cam sensor harness extension is needed for the front-mounted Gen 4 cam sensor
• A small modification to the crank sensor connector is required; see the crank connector section of Link's installation manual
• Most Gen 4 engines need injector adapters to the USCar connector (Link 101-0287); check your injector connector
• Factory Gen 4 knock sensors need the LS Gen 4 Knock Adapter Loom (101-0306)
• A factory Gen 4 MAP sensor needs a Link adapter loom (see 101-0308), or use a Link MAP sensor, which the harness supports directly
• Early truck engines with Multilec injector connectors also need adapters
