ECUmaster PMU-16 Motorsport Wiring Loom

Motorsport-grade ETFE (MIL-W-22759/16) wiring loom engineered specifically for the ECUmaster PMU-16 Power Management Unit (PDM).

This wiring loom is designed for builders who require a reliable, professional-grade electrical foundation for an ECUmaster PMU-16–based power distribution 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 current load are part of the operating environment.

The ECUmaster PMU-16 provides fully programmable, solid-state power management for modern ECU-controlled vehicles, and this loom removes the compromises commonly found in universal or automotive-grade wiring.

Designed Specifically for ECUmaster PMU-16

This loom is pinned exclusively for the ECUmaster PMU-16. Every circuit is allocated correctly for the PMU’s power inputs, outputs, control signals, and CAN communications — with no universal pinouts, repurposed circuits, or guesswork.

The result is a clean, predictable wiring system that supports reliable power distribution, stable CAN communication, and long-term electrical durability in demanding motorsport environments.

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 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 ECUmaster PMU-16 loom is supplied in an unterminated (flying lead) configuration as standard, allowing complete flexibility for circuit allocation, load grouping, and routing.

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

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

Suitable Applications

This loom is suitable for:

• Motorsport and competition vehicles

• ECU + PMU–based electrical architectures

• Circuit racing, time attack, drag racing, and rally

• High-output electrical systems and full custom builds

• 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.

What’s Included

• ECUmaster PMU-16 connector(s)

• Pre-wired ETFE (MIL-W-22759/16) wiring loom

• Built to order and quality checked prior to dispatch

Fuses, loads, ECUs, sensors, and actuators 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 Modern ECU + PMU Systems

The ECUmaster PMU-16 is a motorsport-grade power management unit designed for fully programmable vehicle electrical systems. This loom is built to support it properly — without shortcuts, compromises, or unnecessary complexity — in demanding motorsport and performance environments.
