Restore reliable electrical connections through the door with the Standard Ignition Door Harness Connector S1901. It installs as a direct-fit replacement for the 2006-2008 Dodge Ram 1500, 2006-2009 Dodge Ram 2500, 2006-2010 Dodge Ram 3500, 2008-2010 Dodge Ram 4500, and 2008-2010 Dodge Ram 5500.

A door harness connector joins the wiring that passes between the vehicle body and the door, carrying the electrical signals for door-mounted components such as switches, power locks, windows, and mirrors. Over time the terminals can corrode or the pins and connector body can crack, leading to intermittent or lost operation of those circuits. If a failed connector is the cause of your trouble, this replaces it.

  • Function: connects the door-side wiring to the body harness to pass electrical signals through the door.
  • Direct fit: designed to replace the original connector on the listed applications.
  • Signs it may need replacing: intermittent or dead door switches, locks, windows, or mirrors, and corroded or damaged terminals.
