Connector
Mack

A distinct electrical connector suitable for vehicle harness systems on heavy-duty Mack equipment, this part emphasizes weather sealing and high-reliability contact performance. It provides precise alignment with its mate, a reinforced locking interface, and copper alloy contacts designed for repeated connect/disconnect cycles without degradation. The connector supports stable power delivery to critical systems such as sensors and actuators, even in damp or dusty environments commonly encountered on long routes or off-road service. Proper assembly includes ensuring the seals are intact and the housing is latched to prevent micro-movements that could induce electrical noise. Regular inspection should catch any loose terminals or cracked housings that could lead to intermittent faults. Source One Parts Center presents this specialized connector as a robust option for Mack harness assemblies.
