Designed for CPC2 and CPC4 Harness Repair
This CPC4 harness repair kit is built to handle the unique wiring challenges of Freightliner CPC modules. Whether you’re repairing a CPC2 harness connector or replacing a missing CPC4 wiring connector, this kit ensures you have the correct contacts and hardware for the job.
Because trucks may be wired differently, you’ll need basic knowledge to determine which wire in your OEM harness connects to which cavity of the CPC connector. If you’re not comfortable tracing wires, we recommend working with a qualified mechanic.
