Metra Electronics 702001

When upgrading an aftermarket stereo in a vehicle, cutting factory wires can lead to electrical faults, lost dashboard signals, and a tedious reinstallation process. Manufactured by Metra Electronics—the gold standard in 12-volt vehicle integration accessories—the Aftermarket Radio Wiring Harness (Part No. 70-2001) is engineered specifically to plug directly into select vehicle factory harnesses without requiring you to cut or splice any original factory wiring.

Part Number Breakdown and Architecture

• Brand / Series (Metra): Metra’s premier installation harness line designed for OEM plug compatibility and color-coded wire standardization.

• Configuration (70-2001): Denotes a specialized vehicle-side wiring adapter featuring a precision-molded factory plug connector on one end and stripped, pre-coded lead wires on the other.

Key Features and Functional Capabilities

Deploying the Metra 70-2001 wiring harness in your head-unit upgrade delivers major operational advantages:

1. Zero Factory Wire Cutting

Plugs directly into the vehicle’s factory radio plug, preserving your original electrical architecture and allowing you to restore the factory stereo easily if needed in the future.

2. Industry-Standard Color Coding

Every wire is clearly marked with its specific function (e.g., solid yellow for 12V constant battery, solid red for accessory ignition, black for chassis ground, and paired colors for front/rear speakers), streamlining bench-splicing.

3. High-Conductivity Copper Wire Leads

Constructed with high-grade stranded copper wire leads that ensure stable current flow and clean audio signal transmission to your speakers.
