Link G4X XtremeX + Terminated LS Engine Harness Bundle, Gen 3 LS1/LS6 Drive-by-Wire (109-9005B)

A ready-to-go way to connect a Link ECU to a Gen 3 (LS1 and LS6) drive-by-wire LS V8. It pairs the G4X XtremeX with the Terminated LS Engine Harness, the LS DBW Adapter Loom and the MAP and knock adapters for the factory Gen 3 sensors. It does not include a fuse and relay box (see 109-9010B) and is not for Gen 4 engines.

In the bundle

• G4X XtremeX wire-in ECU (109-4000), 8 injection and 8 ignition drives, with its USB tuning cable, mounting bracket and quick start guide
• Link Terminated Engine Harness for GM LS Gen 3/4 (101-0300)
• LS DBW Adapter Loom (101-0304)
• LS MAP Adapter Harness (101-0302)
• LS Gen 3 Knock Adapter Loom (101-0305)

Highlights

• Fully programmable e-throttle control, with gear shift throttle blip and anti-lag capability
• Cruise control, traction control, launch control and full gear shift control
• Two independent CAN modules and 30 general-purpose tables (up from 20)
• Advanced closed-loop lambda strategy with dual bank lambda control
• Harness is designed to match the PCLink base map I/O setup, so most engines can be made to run with minimal adjustments
• Harness built with Link's AVSS automotive wire in standard Link colours, tested for pinout, shorts and insulation resistance before shipping
• EV1/JPT injector connectors that plug directly into common LS1 injectors
• Spare I/O on a Spares connector for extra sensors, switches or custom additions
• Sealed JPT terminals (TE Connectivity JPT family) in the chassis connector

Harness connectors

• Pedal connector (drive-by-wire pedal): 5V, sensor ground and two analog voltage inputs
• CAN2 connector for lambda modules, displays, keypads and other CAN devices
• MAP connector for Link MAP sensors (adapters available for factory LS MAP sensors)
• Knock connector for up to two knock sensors (adapters available for Gen 3 or Gen 4 factory sensors)
• Alternator connector for F Body alternators, with the exciter/lamp wire to terminal B
• Trans connector for a reverse switch, DI or other cabin signal
• IAC connector for a 4-wire stepper IAC; if no IAC is used, those channels can serve other functions such as a boost valve or nitrous
• TPS connector for cable-throttle sensors, which can be repurposed on drive-by-wire builds
• DBW connector for drive-by-wire throttle bodies (analog inputs, 5V, sensor ground), which can be repurposed on cable-throttle engines
