The fourth generation of the BMW 7 Series was produced in 2001, 2002, 2003, 2004, 2005, 2006, 2007 and 2008 under the E65 body design. E66 – a longer version of the car was designated, and e67 – armored versions. During this time, the car went through one restyling. We offer information on relay blocks and fuses for bmw e65 and e66 with a detailed description of the circuits.
This BMW version has two main fuse boxes. One is in the cabin, the other is in the trunk.
Passenger compartment fuse box
It is located behind the glove compartment, or as it is also called the glove compartment.
To access, push the cover tab forward and flip up. It will look something like this. 
At the bottom there should be a fuse data sheet with up-to-date information for your model. We offer only general information. Spare fuses and plastic tweezers are located on the mounting block in the trunk.

Your webaddress is called fuseandrelay.com yet I haven’t seen any mention of the relay locations and assignments for the BMW E65/E66. I know there are relays as I have seen three. Two by the trunk power module and one behind the fuse panel behind the glove box. Knowing he locations and assignments of all relays would be extremely helpful when troubleshooting issues such as air conditioner suddenly stops blowing cold air. Kinda difficult to follow process of elimination on compressor clutch function when the electrical components controling power to the clut h can’t be located.
