Detroit Diesel MCM2.1 120-Pin Connector Repair Kit / Pigtail

Product Overview

The Detroit Diesel MCM2.1 120-Pin Connector Repair Kit is designed to replace damaged or failed connectors on Detroit Diesel Motor Control Modules (MCM2.1). This kit allows technicians to repair the connector portion of the harness without replacing the complete engine harness assembly.

It is commonly used when connectors are corroded, cut, melted, or damaged from vibration or previous repairs. By replacing only the connector, you reduce repair time, lower costs, and return the unit to service faster.
