Our EMS Motorsport Grade ETFE MIL-W-22759/16 wiring harnesses are purpose-built for 4860 and 8860 series ECUs 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 EMS ECU pinouts — not universal or generic harnesses.
