FuelTech FT450 Motorsport Wiring Loom

Motorsport-grade ETFE (MIL-W-22759/16) wiring loom engineered specifically for the FuelTech FT450 Engine Control Unit.

This wiring loom is designed for builders who require a reliable, professional-grade electrical foundation for a FuelTech FT450–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.

Thanks to the FT450’s IP-rated sealed enclosure, this loom is equally well suited to off-road, marine, and watersports applications, where exposure to dust, moisture, and harsh operating conditions is unavoidable.

Whether you’re building a competitive drag car, an off-road race vehicle, a marine or watersports application, or a high-performance street build, this loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for FuelTech FT450

This loom is pinned exclusively for the FuelTech FT450 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 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 FT450 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, CAN provisions, and additional outputs 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 FT450 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 Harsh Environments and High-Performance Builds

The FuelTech FT450 is a powerful and compact motorsport ECU with 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.
