FuelTech FT550 Motorsport Wiring Loom

Motorsport-grade ETFE (MIL-W-22759/16) wiring loom engineered specifically for the FuelTech FT550 Engine Control Unit.

This wiring loom is designed for builders who require a reliable, professional-grade electrical foundation for a FuelTech FT550–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 system complexity are part of the operating environment.

Thanks to the FT550’s sealed, IP-rated enclosure, this loom is also well suited to off-road, marine, and watersports applications, where exposure to dust, moisture, and harsh conditions is unavoidable.

Whether you’re building a serious drag racing program, an off-road competition vehicle, a marine or watersports setup, or a high-end performance street car, this loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for FuelTech FT550

This loom is pinned exclusively for the FuelTech FT550 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 FuelTech peripherals, power management, and CAN-based accessories.

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 harsh motorsport, off-road, and marine environments.

Key benefits include:

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

• Thin, lightweight insulation for compact, low-bulk 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 FT550 loom is supplied in an unterminated (flying lead) configuration as standard, allowing complete flexibility for engine layout, sensor selection, power distribution, and routing.

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

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

Suitable Applications

This loom is suitable for:

• Drag racing and roll racing

• Off-road and rally applications

• Marine and watersports builds

• High-performance street and competition vehicles

• Engine swaps and custom conversions

• 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

• FuelTech FT550 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 High-Power and Harsh-Environment Builds

The FuelTech FT550 is a high-capability motorsport ECU housed in a sealed, IP-rated enclosure. This loom is designed to support it properly — without shortcuts, compromises, or unnecessary complexity — across motorsport, off-road, and marine environments.
