FAQ Q: Why do I need a harness plug kit after deleting my Ram Cummins 6.7L? A: When sensors are unplugged from the exhaust and engine bay, open factory wiring sockets are exposed to moisture, road salt, and mud. These plugs keep the electrical contacts completely dry and clean, preventing short circuits and pin corrosion. Q: How do I select the correct harness plug kit for my Ram truck? A: Simply select your truck's exact model year range from the dropdown menu above. Dodge updated sensor plug shapes across different Cummins generations (2007.5–2009, 2009.5–2012, 2013–2015, 2016–2018, and 2019–2024), and each kit is tailored for exact plug-and-play fitment. Q: My Ram 6.7L Cummins is a 2009 model. How do I know whether to select the 2007.5–2009 or 2009.5–2012 variant? A: Dodge updated chassis sensor connectors mid-2009: check your driver-side door sticker and select 2007.5–2009 (Early) if your truck was built in 06/09 or earlier (1st-gen square plugs), or 2009.5–2012 (Late) if built in 07/09 or later (4th-gen locking-tab plugs). Q: Do I need any special tools or silicone sealant to install this harness plug kit? A: No tools or messy sealants required. Installation is 100% tool-less and plug-and-play—simply push each cap onto the open factory harness connector until you hear or feel a firm click.
