Detroit Diesel Electronic Controls DDEC ECM Engine Control Module - Used, Untested

Detroit Diesel electronic engine control module (ECM/ECU) with "Detroit Diesel Electronic Controls" cast into the aluminum housing, four corner isolator mounts, and a three-connector harness face — consistent with the Detroit DDEC III / DDEC IV family used on Series 60 and 71/92 series engines in truck, industrial, generator, and marine installations. Application: Detroit Diesel DDEC-equipped engines; the specific engine model, rating, and calibration are NOT verified because the OEM data label is missing/painted over. May fit DDEC III/IV applications; buyer must confirm. Condition: Used take-off, untested. Painted off-white with blue paint/tape residue on the lid, surface dirt, chipped paint, and light surface corrosion around the connector shelf. Connectors and pin blocks look complete and the housing appears sealed and uncracked. No power-up, bench test, or calibration read has been performed — offered as an untested unit / core. The only number on the unit is an inventory-style barcode label (5352000838 R), which is not a Detroit service part number. DDEC modules are calibration-specific and normally require dealer programming to the target engine serial number. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
