Whether you're performing a fleet repair or restoring a single truck, this kit offers a practical solution for CPC connector repairs.

Features & Benefits

Complete Harness Repair Solution

This kit includes the four primary connector housings used on CPC2 and CPC4 modules. Therefore, installers can quickly replace damaged or missing connector assemblies without replacing the entire harness.

Pre-Crimped Terminals Included

Each wire includes a pre-crimped terminal. Consequently, installers can save time and avoid purchasing specialized crimping tools.

Automotive-Grade TXL Wire

We use durable 18 AWG TXL automotive wire designed for heavy-duty truck environments. As a result, the repair can withstand vibration, temperature changes, and demanding operating conditions.

Pinout Information Included

We provide CPC2 and CPC4 pinout reference information to assist with connector population and cavity identification. In addition, the supplied documentation helps installers verify connector locations before making repairs.

Cost-Effective Alternative to OEM Harness Replacement

OEM harness replacements can be expensive. Fortunately, this repair kit allows you to replace only the damaged connector section, which helps reduce downtime and repair costs.

Compatible Applications

Repair facilities, fleet maintenance departments, and owner-operators commonly use this kit on:

• Freightliner Cascadia
• Freightliner Columbia
• Freightliner Coronado
• Freightliner Business Class M2
• Freightliner 114SD
• Freightliner 122SD

Additionally, this kit supports many applications utilizing:

• Detroit Diesel CPC2 Modules
• Detroit Diesel CPC4 Modules

Because vehicle configurations vary, always verify connector style and pinout requirements before ordering.

Installation Information

Because wiring configurations vary by truck model, year, engine, and application, installers must verify all wire locations before populating the connectors.

Therefore, review the supplied pinout information before beginning the repair. Next, identify each wire and confirm its cavity location before making any electrical connections.

If you are unfamiliar with wiring repairs or circuit tracing, consult a qualified technician. Doing so can help prevent wiring errors and unnecessary downtime.
