12-Pin Car Audio Radio Male to Female Extension – Automotive Cable Assembly
- Stereo System Extension: Configured as a 12-Pin Male to Female pass-through adapter, ideal for extending factory radio wiring or creating space behind the dashboard for aftermarket head units.
- Non-Destructive Install: Allows for "Plug and Play" modification, enabling you to tap into power or speaker lines without cutting or splicing the original vehicle harness.
- High-Fidelity Audio: Assembled with high-purity copper conductors to minimize resistance, ensuring clear sound transmission to speakers and subwoofers.
- Universal 12-Pin Fitment: Compatible with various 12-pin automotive radio connectors commonly found in older Japanese import vehicles or specific aftermarket stereo brands.
- Standard Color Coding: Wires are color-coded to industry standards (Power, Ground, Accessory, Speakers) to simplify identification during installation or troubleshooting.

What information do you need to provide a quote for a custom wire harness?
To provide an accurate quote and lead time, please provide:
- Technical Drawing or Diagram: Showing pinouts, lengths, and tolerances.
- Bill of Materials (BOM): Listing specific connectors (MPN) and wire gauges (AWG).
- Estimated Annual Usage (EAU): Helping us optimize pricing for your volume. Note: If you do not have a formal drawing, our engineering team can help create one based on your physical sample.
Can you suggest cost-saving alternatives for expensive connectors (e.g., TE, Molex, JST)?
Yes. We offer variety of alternative components.
We have extensive supply chain relationships in Taiwan and can suggest"Functionally Equivalent"alternatives that are fully compatible with major brands like TE, Molex, or JST but at a significantly lower cost. We will provide datasheets and samples of the alternative components for your approval before production.
How do you ensure quality control for custom cable assemblies?
Every single cable assembly undergoes rigorous testing before leaving our Taiwan facility. Our standard QC process includes:
- 100% Continuity Testing: Ensuring no opens, shorts, or miswires.
- Pull Force Testing: Verifying crimp strength.
- Visual Inspection: Checking for cosmetic defects and label accuracy.
- Hi-Pot Testing: Available upon request for high-voltage applications to ensure insulation integrity.
