This is a brand new 72-bit pin connector for the Nintendo NES front loader [NES-001]. The most common reason for the Nintendo NES system to fail is a faulty 72-bit pin connector. There are two types of pin connectors on the market today. One that features a tight grip that makes inserting and removing games hard and another that has a looser grip that matches the original specifications. Our pin connectors match the original grip strength. A step-by-step color installation guide is available for download.
