Link XtremeX Motorsport Wiring Loom

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

This wiring loom is designed for builders who require a high-capability, professional-grade electrical foundation for a Link XtremeX–controlled engine. Hand-built using MIL-W-22759/16 motorsport-grade ETFE wire, it is intended for advanced performance and motorsport applications where heat, vibration, electrical noise, and increased system complexity are part of the operating environment.

The Link XtremeX offers extensive I/O capacity and advanced control functionality, making it well suited to serious competition and high-output performance builds. This loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for Link XtremeX

This loom is pinned exclusively for the Link XtremeX ECU. Every circuit is allocated correctly for the ECU’s engine management inputs, outputs, power supply, and 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 devices such as dashes, PDMs, and expansion modules.

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 performance wiring systems.

Key benefits include:

Excellent resistance to heat, fuels, oils, and automotive chemicals
Thin, lightweight insulation for compact 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 Link XtremeX 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 performance and motorsport vehicles
Circuit racing, time attack, drag racing, and rally
High-output and complex engine management systems
Engine swaps and full custom builds
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 matter.
