Wolf V500 Motorsport Wiring Loom

Motorsport-grade ETFE (MIL-W-22759/16) wiring loom engineered specifically for the Wolf V500 Engine Control Unit.

This wiring loom is designed for builders who require a robust, professional-grade electrical foundation for a Wolf V500–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 Wolf V500 offers expanded control capability over entry-level ECUs, making it suitable for more demanding performance and competition builds. This loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for Wolf V500

This loom is pinned exclusively for the Wolf V500 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 accurate sensor data, stable ECU operation, and long-term electrical reliability.

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, tidy 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 Wolf V500 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 vehicles

• Motorsport and competition builds

• Engine swaps and custom conversions

• Turbocharged and naturally aspirated engines

• Track day, circuit, and drag racing applications

• 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

• Wolf V500 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.
