Here is the ford part number for my f150 lariat: bb5z-19a487--ba. This is the cover for the 12v receptacle. Inside the receptacle there are two flanges you have to push closed to extract it. There is a special tool for it. The part number for it is 501-039. You can google it and it is available at several places. Once you have it you insert into the receptacle and pull it out. There will be two wires on the back. Just unplug the wires, take off the old cover, put on the new ones, reattached the two wires ( they just snap off and on) and reinsert the receptacle. Don't need a tool for this just push it back in. Make sure it snaps in ok. Here is the email address of the guy who sent me pictures out of the ford service manual explaining the process: Henry Blau <[email protected]
