Our Haltech Motorsport Grade ETFE MIL-W-22759/16 wiring harnesses are purpose-built for all Haltech Platinum, Elite and Nexus series ECUs and PDMs used in motorsport, performance street builds, and professional engine swaps.

Each loom is hand-built using race-grade M22759/16 ETFE wire and designed specifically for Haltech ECU pinouts — not universal or generic harnesses.
