The E65/E66 is the factory chassis code for the fourth generation of the BMW 7 Series, manufactured from 2001 to 2008. Over its seven-year production run, approximately 330,000 vehicles were built. This article provides a comprehensive overview of the power distribution and fuse box diagrams for the BMW E65/E66 (7 Series, 4th generation, encompassing the 730d, 730i, 735i, 740d, 740i, 745d, 750i, 760Li, and 760i models) across the 2001 through 2008 model years.
This guide details the locations and provides images of the power distribution boxes. The fuses designated for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold for quick reference.
