Installation Notes and Tips

Verify connector shape, terminal style, and wire count before installation. Match the existing injector plug to the rectangular, 2-wire configuration and confirm the vehicle application against the fitment list. Use proper splice and crimp practices when joining the repair connector, and inspect the harness for additional heat or abrasion damage before completing the job.
