Protect Your CPC4 From Theft

CPC4 modules are frequently targeted by thieves because of their value and demand. Removing the module when the truck is parked is one of the most effective theft prevention strategies.

The CPC4 quick-release harness makes this process easy by allowing drivers to disconnect the module quickly and store it safely when the vehicle is unattended.

This helps protect against:

• CPC4 module theft

• expensive module replacement

• truck downtime

• costly repairs and programming

Prevent Damage to Your OEM Harness

Repeatedly unplugging the factory CPC4 connector can cause premature wear because the OEM harness is not designed for daily disconnect cycles.

This quick-release harness acts as an intermediary connection, allowing you to remove your CPC4 module without stressing the factory wiring harness.

Benefits include:

• reduced wear on OEM connectors

• improved long-term harness durability

• faster removal and installation

Required Connector Photo Verification Before Production

IMPORTANT: Customers must send a clear picture of their existing CPC4 connector to verify the correct harness configuration.

Even trucks of the same year and model may have different CPC4 wiring configurations. To help ensure we manufacture the correct harness for your truck, please follow these steps:

1. Take a clear picture of your CPC4 connector showing the pin and cavity arrangement. Make sure pins are visible—try covering the back with something dark so the pins stand out clearly.

3. Include your order number so we can match your pictures to your purchase.
