Emtron KV12 Motorsport Wiring Loom

Motorsport-grade ETFE (MIL-W-22759/16) wiring loom engineered specifically for the Emtron KV12 Engine Control Unit.

This wiring loom is designed for builders who require a high-capacity, professional-grade electrical foundation for an Emtron KV12–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 complex engine configurations are part of the operating environment.

The Emtron KV12 is purpose-built for V10, V12, and other high-cylinder-count engines, and this loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for Emtron KV12

This loom is pinned exclusively for the Emtron KV12 ECU. Every circuit is allocated correctly for the ECU’s extensive 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-current motorsport wiring systems required by large, multi-bank engines.

Key benefits include:

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

• Thin, lightweight insulation for compact, high-channel-count 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 KV12 loom is supplied in an unterminated (flying lead) configuration as standard, allowing complete flexibility for engine layout, injector and ignition configuration, sensor placement, and routing.

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

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

Suitable Applications

This loom is suitable for:

• V10, V12, and other high-cylinder-count engines

• Elite-level motorsport and competition vehicles

• Circuit racing, endurance racing, and high-end performance builds

• Engine swaps and full custom projects

• Professional race teams and specialist motorsport 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

• Emtron KV12 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.
