FuelTech FT700 Motorsport Wiring Loom

Motorsport-grade ETFE (MIL-W-22759/16) wiring loom engineered specifically for the FuelTech FT700 Engine Control Unit.

This wiring loom is designed for builders who require a no-compromise, professional-grade electrical foundation for a FuelTech FT700–controlled engine. Hand-built using MIL-W-22759/16 motorsport-grade ETFE wire, it is intended for elite-level motorsport and extreme performance applications where heat, vibration, electrical noise, and system complexity are part of the operating environment.

With its sealed, IP-rated enclosure, the FT700 is equally at home in drag racing, off-road, marine, and watersports applications, where reliability in harsh conditions is critical.

Whether you’re building a top-tier drag racing program, an off-road competition vehicle, a marine or watersports setup, or a cutting-edge performance build, this loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for FuelTech FT700

This loom is pinned exclusively for the FuelTech FT700 ECU. Every circuit is allocated correctly for the ECU’s extensive engine management inputs, high-current outputs, power supply, and advanced multi-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 FuelTech power management, data logging, traction control, and CAN-based vehicle systems.

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.

Key benefits include:

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

• Thin, lightweight insulation for compact, low-bulk, 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 FT700 loom is supplied in an unterminated (flying lead) configuration as standard, allowing complete flexibility for engine layout, sensor selection, power distribution, and advanced CAN integration.

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

Custom terminations, wire lengths, multi-CAN provisions, high-current outputs, and additional system integrations can be discussed prior to ordering if required.

Suitable Applications

This loom is suitable for:

• Professional and elite-level drag racing

• Extreme horsepower and competition vehicles

• Off-road and rally competition

• Marine and watersports applications

• Advanced engine swaps and custom conversions

• 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

• FuelTech FT700 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 FuelTech Systems

The FuelTech FT700 is the flagship ECU in the FuelTech range, designed for the most demanding motorsport and performance applications. This loom is built to support it properly — without shortcuts, compromises, or unnecessary complexity — in the harshest environments.
