Need Wiring Harness for DDM 9W7Z-15K602-C
 

I have a 2010 Mercury Grand Marquis Ultimate Edition with no heated seats, Is the DDM on top the right Drivers Door Module? If so, where do I find the wiring harness for it. I need the part number and location.
My other question is do i have to go to a Ford dealer to get the old module info or data transferred before they put in the new one? My old module barely works as power locks, trunk, dome light, power mirror dont work.
