Injepro T4000 Motorsport Wiring Loom

Motorsport-grade ETFE (MIL-W-22759/16) wiring loom engineered specifically for the Injepro T4000 Engine Control Unit.

This wiring loom is designed for builders who require a no-compromise, professional-grade electrical foundation for an Injepro T4000–controlled engine. Hand-built using MIL-W-22759/16 motorsport-grade ETFE wire, it is intended for advanced motorsport and high-performance applications where heat, vibration, electrical noise, and system complexity are part of the operating environment.

The Injepro T4000 is the most advanced and highest-capability ECU in the Injepro range, offering extensive I/O capacity, advanced control strategies, and modern CAN-based integration. This loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for Injepro T4000

This loom is pinned exclusively for the Injepro T4000 ECU. Every circuit is allocated correctly for the ECU’s extensive engine management inputs, outputs, power supply, and advanced CAN communications — with no universal pinouts, repurposed circuits, or guesswork.

The result is a clean, predictable wiring system that supports accurate sensor data, stable ECU operation, and reliable integration with CAN-based systems including dashes, power management modules, and data logging devices.

Built Using Motorsport-Grade ETFE Wire (MIL-W-22759/16)

MIL-W-22759/16 ETFE wire was originally developed for aerospace and military applications and is ideally suited to high-density, high-channel-count motorsport wiring systems.

Key benefits include:

• Excellent resistance to heat, fuels, oils, and automotive chemicals

• Thin, lightweight insulation for compact, low-bulk looms despite high I/O density

• High durability under vibration and continual movement

• Reduced risk of insulation degradation over time

This wire is selected for reliability — not cost.

Terminated or Unterminated Options

This Injepro T4000 loom is supplied in an unterminated (flying lead) configuration as standard, allowing complete flexibility for complex engine layouts, sensor arrays, and advanced system integration.

A pin placement sheet showing wire numbers is available to download to assist with installation.

Custom terminations, wire lengths, additional I/O provisions, and CAN integration requirements can be discussed prior to ordering if required.

Suitable Applications

This loom is suitable for:

• Advanced motorsport and competition vehicles

• Circuit racing, drag racing, and endurance builds

• High-output and complex engine management systems

• Engine swaps and full custom projects

• Professional race teams and specialist performance workshops

This is not a vehicle-specific plug-and-play harness. It is intended for advanced custom installations where control, reliability, and electrical integrity are critical.

What’s Included

• Injepro T4000 ECU connector(s)

• Pre-wired ETFE (MIL-W-22759/16) wiring loom

• Built to order and quality checked prior to dispatch

Sensors, actuators, PDMs, and the ECU are not included.

Lead Time

Each loom is hand-built to order. Typical lead time is displayed at checkout and may vary during busy periods.

If your build has a fixed deadline, please contact us prior to ordering.

Built to Support Flagship Injepro Systems

The Injepro T4000 is the flagship ECU in the Injepro range, designed for the most demanding motorsport and high-performance applications. This loom is built to support it properly — without shortcuts, compromises, or unnecessary complexity — while meeting professional motorsport wiring standards.
