Ford Sierra was produced in 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993 and 1994. During this time, the Ford Sierra model range has been modernized twice, respectively, and there may be several box diagrams. In our material, we will show a designation of the Ford Sierra fuse boxes and relays with boxes diagrams and photographs. Let’s highlight the fuse responsible for the cigarette lighter.
The design of the boxes may differ from the one shown and depends on the year of manufacture of the Ford Sierra and the country of delivery. The current assignment of the fuse and relay boxes will be printed on the back of the protective cover.
