Syvecs S7-I Motorsport Wiring Loom

Motorsport-grade ETFE (MIL-W-22759/16) wiring loom engineered specifically for the Syvecs S7-I Engine Control Unit.

This wiring loom is designed for builders who require a highly capable, professional-grade electrical foundation for a Syvecs S7-I–controlled engine and vehicle system. 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 integration are part of the operating environment.

The Syvecs S7-I is a powerful standalone ECU offering advanced engine management and CAN-based integration, and this loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for Syvecs S7-I

This loom is pinned exclusively for the Syvecs S7-I 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 CAN-based devices such as dashes, PDMs, and expansion modules.

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 motorsport wiring systems.

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 Syvecs S7-I loom is supplied in an unterminated (flying lead) configuration as standard, allowing complete flexibility for engine layout, sensor selection, and system routing.

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

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

Suitable Applications

This loom is suitable for:

• High-performance street and track vehicles

• Motorsport and competition builds

• Engine swaps and custom conversions

• ECU + PDM–based electrical systems

• 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

• Syvecs S7-I 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.

Built to Support Advanced Syvecs Systems

The Syvecs S7-I is a highly capable motorsport ECU designed for advanced engine control and CAN-based system integration. This loom is built to support it properly — without shortcuts, compromises, or unnecessary complexity.
