TE Connectivity 368255-1 121-Way ECU Pin Header Black

The Component: Genuine TE Connectivity / AMP OEM 121-position PCB right-angle male header assembly / High-density hybrid ECU & Powertrain Control Module interface enclosure plug / 4-bay multi-key receptacle profile / Board-mount solderable male tab terminal pins accepting 0.64mm signal and 1.5mm / 2.8mm power contacts / Molded from glass-reinforced, heat- and chemical-resistant Polybutylene Terephthalate (PBT) resin with perimeter sealing gasket / Component Part Number: 368255-1 / Alternate OEM Identifiers: TE 368255-1 / 3682551 / AMP 121-Pin ECU Header / 121-Way PCM Header / 121-Pin Engine Control Unit Connector.

Applications & Fitment: Heavy-duty waterproof multi-pin ECU board header engineered for Engine Control Units, Transmission Control Modules (TCM), and Body Control Units across automotive, commercial vehicle, agricultural, and industrial equipment platforms. Designed for direct soldering onto main ECU PCBs and mechanical mounting to cast aluminum module enclosures. Features 121 male contact pins arranged across four distinct keyed plug bays to prevent mis-mating during vehicle assembly. Mates with corresponding 121-way female harness plug connector families (such as TE 368257-1 series). Widely specified across global OEM engine management systems (including Bosch, Continental, and VAG ECU enclosures) for managing fuel injection, ignition timing, CAN-bus communications, and sensor monitoring under severe engine compartment thermal and vibrational conditions. Essential component stock for ECU repair technicians, engine reconditioners, motorsport wiring harness manufacturers, and trade distributors.
