I had a tire blow out goin 90+ on the highway. ... it ripped out my ac blower motor and battery Junction box (fuse box under hood).... ripping and tossing wires all over the freeway.... I tried to pick them all up but after trying to reconnect wat I had left I realized I was missing allot. ... I went to junk yard got a new box and some wiring harness from a 2010 taxi and a police car. They are not exactly the same so I'm in need of a diagram of the battery Junction box that shows color codes of my words that I need for 2007 MGM LS.. . power seats, digital dash, heated mirrors. Any help pls!

The closest thing we have is a Battery Junction Box layout in the 1998 to 2011 Crown Victoria fuse and relay charts. It shows where the relays, diodes and fuses sit in the underhood box (Ford base part 14A003). It is not dated to a model year, and the other charts on that page are from 1998 and 2000, so compare it against the layout molded into the lid of your box before trusting it on a 2007:

For the power seats, the wiring page for the same generation has a pinout of the C312 passenger seat connector from a 2007 Crown Victoria, the Grand Marquis' sister car. Check the wire colors against your own connector:

With harness pieces from a taxi and a police car, match each wire by its circuit at both ends rather than assuming the donor harness is laid out like yours. Those fleet cars were often built with different equipment from a Grand Marquis LS.
