Haltech HP4 Ignition Driver Motorsport Wiring Loom

Motorsport-grade ETFE (MIL-W-22759/16) wiring loom engineered specifically for the Haltech HP4 Ignition Driver.

This wiring loom is designed for builders who require a reliable, professional-grade electrical foundation for a Haltech HP4–based ignition 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 high current loads are part of the operating environment.

The Haltech HP4 provides four high-current ignition outputs for driving external ignition coils, and this loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for Haltech HP4

This loom is pinned exclusively for the Haltech HP4 Ignition Driver. Every circuit is allocated correctly for the driver’s power supply, trigger inputs, and high-current ignition outputs — with no universal pinouts, repurposed circuits, or guesswork.

The result is a clean, predictable wiring system that supports reliable ignition performance 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 ignition 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 HP4 loom is supplied in an unterminated (flying lead) configuration as standard, allowing complete flexibility for ignition coil selection, placement, and routing.

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

Custom terminations, wire lengths, and ignition output grouping can be discussed prior to ordering if required.
