Build Sheet Location Synopsis; Locations vary because it depended upon who threw it in the Bronco on the production line vs. those who took time to place it same place for 18 years: "...under the driver's or passenger side carpet, in the fiberglass top hidden behind the rear trim piece, driver's side in a 79 by Ziggy; was under the rubber mat under the driver's seat in a 78 by Scoop; under my carpet on the right side in the back in a 92 by M. Cardholder; under the carpet directly behind the front passenger seat, Under the cardboard spacer sheet/heat shield in an 88 by Dustball; under the drivers side of your front seat between the seat springs and the cushion in an 86 F 150 by Hoxviii; underneath the carpet under the drivers seat and another in the back end underneath the carpet in an 88 by Xris; Ive found them in the back seat front seat Passenger floor Board and head liner. Gently feel your back seat for paper under the vinyl. Same with the back and then under the seats. Possibly under passenger carpeting rubber mat in a 78 by F1rocco; under my rear deck carpet and padding, taped to the bed in an 89 by Buckin' 89Bronco..."
Some info can be readily viewed on the build sheet, but I have not been able to oibtain a good Legend from Ford, and probably never will.
