The Component: Genuine TE Connectivity 1544458-1 2-way unsealed terminal housing block. Positive Lock / 8.0mm (.315 in) connector series classification / Molded Jet Black premium Polyamide (PA) / Loose piece format.
Applications & Fitment: Designed as a heavy-duty, high-current wire-to-wire or wire-to-device receptacle housing. This unsealed block acts as the secure physical carrier for 8mm wide Positive Lock female terminals, featuring an integrated primary locking mechanism that prevents contact back-out under heavy operational vibration. Commonly deployed across European and global heavy commercial vehicle, passenger vehicle, and appliance power distribution architectures—including Ford electrical networks—for high-load paths such as HVAC blower motor systems, primary heating ventilation circuits, cabin main distribution feeds, and main relay line junctions. Highly vulnerable to tab distortion if forced onto non-standard 8mm mating blades without proper terminal alignment, or if subjected to direct spray environments without secondary external protective boot shielding.
