G4X XtremeX ECU + Terminated LS Engine Harness Drive-by-Wire Bundle
G4X XtremeX ECU + Terminated LS Engine Harness Drive-by-Wire Bundle
A complete Link ECU and wiring package for Gen 3 / Gen 4 LS V8 engines with drive-by-wire (electronic) throttle. It pairs the G4X XtremeX with Link's terminated LS engine harness and the adapters needed for your engine, so the factory sensors plug straight in with no loom building.
The harness is laid out to match Link's PCLink LS base maps, so most engines start and idle with only minor adjustments before tuning.
Before you buy
- 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).
- Most Gen 4 engines use USCar injector plugs and need adapters (Link PN 101-0287).
- 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.
