Haltech Plastic AMP Superseal Connector Waterproofing/Blanking Pins - Pack of 10

These are Haltech AMP Superseal connector blanking pins, sold in a pack of 10. They're designed to seal off unused cavities in your AMP Superseal connectors. This is a simple but important step to keep moisture, dirt, and other contaminants out of your wiring harness. Keeping those cavities clean and dry helps prevent corrosion and ensures reliable electrical connections down the road.

When you're wiring up an engine management system or any custom setup, you might not use every pin in a connector. Instead of leaving those open spots exposed, you can pop one of these blanking pins in. They fit snugly into the connector cavity, creating a solid seal. It's a small detail, but it makes a big difference in the long-term reliability of your electrical system, especially in harsh engine bay environments.
