BD Diesel Fuel Injector Electrical Connectors With Pigtail Wires| 4-Pack | 17-23 GM Duramax L5P

These plastic electrical connectors are known to crack or break during the process of replacing your fuel injectors. Another common problem is a poor connection due to terminal fretting, which can cause fault codes P0201 to P0208. That's why it's a good idea to replace these connectors when you replace your fuel injectors. They even come with heat-shrink butt connectors for an air tight seal to keep dirt and moisture out for a reliable long term repair!
