Mercury Milan 2006-2009 uses a Smart Junction Box in the passenger compartment and a Power Distribution Box in the engine compartment. The under-hood arrangement differs between 2006-2007 and 2008-2009, so both tables are kept separately.
For the facelift and Hybrid version, see Mercury Milan and Milan Hybrid 2010-2011.
