Link G4X StormX ECU LS Gen 3 Cable Throttle Bundle with Fuse Box & Relay

Link G4X StormX ECU LS Gen 3 Cable Throttle Bundle with Fuse Box & Relay

A ready-to-go engine management package for GM Gen 3 LS engines including LS1 and LS6 with cable throttle, supplied with a fuse box and relay setup.

This bundle combines the Link G4X StormX ECU with a terminated LS engine harness, the required adapter looms and the Link fuse and relay box, giving you a more complete installation package without having to build the engine management wiring from scratch.

The terminated harness is designed around Link's PCLink base map I/O setup, helping reduce initial wiring and configuration work and providing a straightforward starting point for final setup and tuning.

Terminated LS Engine Harness

The supplied terminated harness is designed to match the PCLink base map I/O configuration, helping get most supported engines running with minimal changes before final tuning.

The harness also provides spare inputs and outputs for additional sensors, switches and other vehicle functions.

Fuse Box and Relay Setup

This version of the bundle includes the Link LS fuse and relay box.

With the fuse box fitted, the harness includes main chassis flying leads for essential power and control connections.

These include:

• Main battery positive feed for ECU power

• ECU-controlled cooling fan output

• ECU-controlled fuel pump output

• Ignition switch input

The cooling fan and fuel pump outputs are rated at 20A continuous.

Harness Connections

The harness includes dedicated connections for:

• DBW pedal

• CAN2 devices

• MAP sensor

• Knock sensors

• Alternator

• Transmission signals

• 4-wire Stepper IAC

• Cable Throttle TPS

• DBW throttle body

Some unused channels can also be repurposed for additional functions such as boost control, nitrous control or other auxiliary outputs.

Spare Inputs and Outputs

A dedicated Spares connector is provided for additional sensors, switches and custom functions.

The chassis connector uses sealed JPT terminals for a reliable installation.

Cable Throttle Setup

This bundle is intended for Gen 3 cable throttle LS applications.

The supplied Stepper Adapter Harness supports the factory-style idle control arrangement, while the TPS connection is provided for cable throttle position sensing.

MAP Sensor Connection

The LS MAP Adapter Harness allows connection to the factory LS MAP sensor arrangement while using the terminated Link engine harness.

Knock Sensor Connection

The included Gen 3 Knock Adapter Loom allows the factory Gen 3 knock sensors to be connected to the StormX ECU's onboard knock control.

CAN Connection

A dedicated CAN2 connection is provided for compatible CAN devices including:

• Lambda modules

• Displays

• Keypads

• Other CAN-based accessories

PCLink Base Map

A Gen 3 Cable Throttle base map is available for use with the G4X StormX / XtremeX platform.

This provides a useful starting point for setup but is not a finished vehicle calibration.

Please Note

Professional installation and tuning are recommended.

The supplied base map is intended to assist with initial setup and starting only. Final ECU configuration and calibration must be carried out to suit the individual engine and vehicle specification.
