Installation Notes and Tips

Verify the vehicle’s column-mounted switch configuration, connector shape, and terminal layout before installation. This US-521 uses a female rectangular connector with 5 male blade terminals and a bolt-on mounting method, so matching the original electrical and mechanical design is important. Confirm fitment for vehicles such as 2007-2018 Jeep Wrangler, 2001-2007 Dodge Grand Caravan, and 2006-2007 Chrysler 300 before replacement.
