This simple kit allows you to repair all four sliders found within your two factory L5P Duramax ECM wiring harness connectors. The factory connector uses a plastic slider to lock the harness connector to the factory ECM. These sliders often become brittle over time and can be damaged when removing the ECM. This kit will allow you to simply repair your connectors without having to replace the entire harness. The process is simple and straightforward and can be done with the harness still in the vehicle in a matter of minutes. We also have a step-by-step video available to help walk you through the repair.
