Link DI Driver-4 Motorsport Wiring Loom

Motorsport-grade ETFE (MIL-W-22759/16) wiring loom engineered specifically for the Link DI Driver-4 Driver Module.

This wiring loom is designed for builders who require a reliable, professional-grade electrical foundation for a Link DI Driver-4–controlled injector/ignition driver module. 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 high switching loads are part of the operating environment.

The Link DI Driver-4 provides four high-current outputs for injector and ignition coil driving, and this loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for Link DI Driver-4

This loom is pinned exclusively for the Link DI Driver-4 Module. Every circuit is allocated correctly for the driver module’s high-current outputs, control signals, power supply, and CAN communications — with no universal pinouts, repurposed circuits, or guesswork.

The result is a clean, predictable wiring system that supports reliable high-current switching, stable communications, and long-term electrical durability.

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-current, high-duty 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 Link DI Driver-4 loom is supplied in an unterminated (flying lead) configuration as standard, allowing complete flexibility for harness routing, driver placement, and system layout.

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

Custom terminations, wire lengths, high-current output grouping, and CAN integration provisions can be discussed prior to ordering if required.

Suitable Applications

This loom is suitable for:

• Motorsport and competition vehicles

• ECU + auxiliary driver modules

• High-current injector and ignition driver systems

• Circuit racing, drag racing, and time attack

• Professional workshops and motorsport fabricators

This is not a vehicle-specific plug-and-play harness. It is intended for custom installations where control, reliability, and electrical integrity matter.
