New OEM Ford Engine Fuse Box Wiring Harness new in the box but it got damaged in shipment - the fuse box is missing a mount but you can transfer the box over. This is in stock, though no longer available from Ford, we have it. This is made for 2011-2012 Mustang 3.7 motor only; it will fit 5.0 also with minor wires added. Ford made 23 different harnesses in 2011-2012 the options differ so it would have less or more wiring than needed but you can add wiring from yours or not use extra on thes. If you are willing to work with it, you can make it work on any option in other words - email us if not sure. If you want exact fit, the sticker on the harness has to match: BR3T-14290-BC, BR3T-12490-CAD OEM # BR3Z-14290-CC, BR3Z-14290-CB???????
