What It Helps Repair

  • Broken or heat-damaged rear light connector terminals
  • Intermittent rear lamp operation caused by poor terminal contact
  • Corrosion at the rear lighting harness connection
  • Loose locking tabs that prevent a secure disconnect/reconnect
  • Damaged pigtail wiring at the tail lamp harness

Installation Notes and Tips

Match the connector to the vehicle-side terminal style before splicing. Use proper butt connectors and sealed wiring practices to maintain the weather-resistant connection. Verify wire routing and terminal engagement after installation to confirm the rear light harness connector locks fully into place.

Quality Assurance

Dorman designs this connector as a service replacement for electrical repair work and accessory installation, with weatherproof terminals and a locking tab for dependable connection retention. It is engineered for a clean installed appearance and consistent fit in the listed Toyota and Lexus applications.
