Supported ECU Platform This wiring harness range is designed specifically for MaxxECU systems and is built to the same motorsport ETFE M22759/16 standard used across all supported ECUs.
Our MaxxECU Motorsport Grade ETFE MIL-W-22759/16 wiring harnesses are purpose-built for the entire MaxxECU series ECUs & PDM20 PDM 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 MaxxECU's pinouts โ not universal or generic harnesses.
