MicroTech LT-16c Motorsport Wiring Loom

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

This wiring loom is designed for builders who require a robust, professional-grade electrical foundation for a MicroTech LT-16c–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, electrical noise, and increased system demands are part of the operating environment.

The MicroTech LT-16c is the most capable ECU in the LT-series, offering expanded I/O capacity to support more complex engine configurations. This loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for MicroTech LT-16c

This loom is pinned exclusively for the MicroTech LT-16c ECU. Every circuit is allocated correctly for the ECU’s engine management inputs, outputs, power supply, and communications — with no universal pinouts, repurposed circuits, or guesswork.

The result is a clean, predictable wiring system that supports stable ECU operation, accurate sensor data, and long-term electrical reliability in demanding applications.

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 higher-density performance and motorsport wiring systems.

Key benefits include:

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

• Thin, lightweight insulation for compact looms despite increased channel count

• 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 MicroTech LT-16c loom is supplied in an unterminated (flying lead) configuration as standard, allowing complete flexibility for engine layout, injector and ignition configuration, and harness routing.

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

Custom terminations, wire lengths, and additional provisions can be discussed prior to ordering if required.

Suitable Applications

This loom is suitable for:

• High-performance street and motorsport vehicles

• Drag racing and roll racing applications

• Multi-cylinder and high-output engines

• Turbocharged and naturally aspirated engines

• Rotary and piston engine platforms

• 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

• MicroTech LT-16c ECU connector(s)

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

• Built to order and quality checked prior to dispatch

Sensors, actuators, 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 MicroTech’s Most Capable LT-Series ECU

The MicroTech LT-16c is the top-tier ECU in the LT-series, designed for builders requiring expanded control and higher system capability. This loom is built to support it properly — without shortcuts, compromises, or unnecessary complexity — while maintaining professional motorsport wiring standards.
