Toyota BCM 30-Pin Extension (90980-12C62) – Automotive Wire Harness & Cable Assembly
- Toyota OEM Compatibility: Precision-engineered to match the 90980-12C62 30-pin connector, commonly used in Toyota and Lexus Body Control Modules (BCM) and ECUs.
- Non-Invasive Extension: Features a Male-to-Female pass-through design, allowing for the installation of accessories or T-harness applications without cutting factory wiring.
- High-Density Signal: Designed to handle 30 individual signal lines in a compact housing, perfect for complex vehicle electronic systems.
- Durable Construction: Built with Sumitomo-style equivalent connectors and automotive-grade terminals to ensure a secure, vibration-resistant connection.
- Custom Wiring Specs: We can customize cable lengths and wire gauges (AVSS/FLRY) to suit specific retrofit projects, remote start installs, or diagnostic tools.

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.
