Link G4X StormX + Terminated LS Engine Harness Bundle, Gen 3 LS1/LS6 Drive-by-Cable (108-9005B)

A ready-to-go way to connect a Link ECU to a Gen 3 (LS1 and LS6) cable throttle LS V8. It pairs the G4X StormX with the Terminated LS Engine Harness plus the stepper, MAP and knock adapters that suit a Gen 3 engine on a cable throttle body. It does not include a fuse and relay box (see 108-9010B) and is not for Gen 4 engines.

In the bundle

• G4X StormX wire-in ECU (108-4000), 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 Stepper Adapter Harness (101-0301)
• LS MAP Adapter Harness (101-0302)
• LS Gen 3 Knock Adapter Loom (101-0305)

Highlights

• Built-in trigger oscilloscope
• Onboard knock control for two knock sensors wired directly to the ECU, no external amplifier required
• Open or closed loop boost control with up to three switchable tables
• Idle valve solenoid or stepper motor control, and rotary oil metering pump control
• Full gear shift control, anti-lag and launch control
• Up to four fully variable closed-loop VVT cams
• 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

Want the fuse and relay box included? Look at the Gen 3 cable throttle bundle with fuse box, 108-9010B. Link points Gen 4 LS engines to a different bundle, 109-9020B.

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
