In a harness that routes near an engine block or through a chassis frame, that positive lock keeps the terminals from backing out. ## Contacts Not Included — Order the Crimp Terminal Separately This housing ships empty. For the receptacle side, the matching Mini-Fit Jr 5559 receptacle housing (dual-row, same 4.20 mm pitch) completes the wire-to-wire pair. No obsolescence notice or successor part is on record. Supply is confirmed at quote time against the BOM quantity through independent distribution.","metaTitle":"Molex Mini-Fit Jr 5559 0039013123","metaDescription":"Molex 0039013123 Mini-Fit Jr 5559 plug housing, 12 circuits, 4.20mm pitch, dual-row, locking ramp.
