Emtron SL4 Motorsport Wiring Loom

Motorsport-grade ETFE (MIL-W-22759/16) wiring loom engineered specifically for the Emtron SL4 Engine Control Unit.

This wiring loom is designed for builders who require a reliable, professional-grade electrical foundation for an Emtron SL4–controlled engine. Hand-built using MIL-W-22759/16 motorsport-grade ETFE wire, it is intended for high-performance and motorsport applications where heat, vibration, and electrical noise are part of the operating environment.

The Emtron SL4 delivers advanced engine management capability in a compact package, and this loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for Emtron SL4

This loom is pinned exclusively for the Emtron SL4 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 modern motorsport environments.

Key benefits include:

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

• Thin, lightweight insulation for compact, high-density looms

• 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 Emtron SL4 loom is supplied in an unterminated (flying lead) configuration as standard, allowing complete flexibility for engine layout, sensor selection, and routing.

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:

• Performance street and track vehicles

• Motorsport and competition builds

• Engine swaps and custom conversions

• Turbocharged, supercharged, and naturally aspirated engines

• Professional workshops and performance fabricators

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

What’s Included

• Emtron SL4 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 deadline, please contact us prior to ordering.

Built to Support Modern Emtron Systems

The Emtron SL4 is a compact yet powerful motorsport ECU designed for modern, CAN-based engine management systems. This loom is built to support it properly — without shortcuts, compromises, or unnecessary complexity — while meeting professional motorsport wiring standards.
