Terminated Engine Harness GM LS GEN3/4
$1,095.00
Link's ready-made engine harness for GM LS V8s, built to connect a G4X StormX or XtremeX ECU to Gen 3 LS1/LS6 or Gen 4 LS2/LS3/LS7 engines. It suits stock engines, swaps and full race builds, and saves the hours of cutting, crimping and labelling a custom loom takes.
It uses one base loom that you adapt to your engine with Link's plug-in adapters. Every harness is tested for pinout, shorts and insulation before it ships.
Before you buy
- Cable throttle needs the LS Stepper Adapter (101-0301); drive-by-wire needs the LS DBW Adapter (101-0304).
- Early truck engines with Multec injector plugs and later USCar/EV6 injectors need adapters (101-0287).
- Gen 4 engines need a cam sensor harness extension for the front-mounted cam sensor.
- The crank sensor connector needs a small modification on Gen 4 engines (see the harness manual).
- Factory Gen 4 knock sensors need the LS Gen 4 Knock Adapter Loom (PN 101-0306).
- A factory Gen 4 MAP sensor needs the LS MAP Adapter plus a Gen 3 to Gen 4 MAP extension, or use a Link MAP sensor, which plugs straight into the harness.
- A fuse and relay box is sold separately (101-0310).
