I need some help locating the fuse box locations on my 1990 xjs convertible.
I know ther are two boxes under the bonnet left side but where are the others and where can I get a description of what is in there?

 

The others are above your shins under removable covers. It should say on the covers' inside what each fuse does.

As Greg mentioned, there are two fuse boxes under the dash. If you look on both the drivers side and passenger side you will find a door panel held on by one plastic screw. Just turn the screw a quarter turn and the panel will come off.
Both panels have fuses and relays. Some of the fuse information is shown of a decal on the back of the access panels. I will post some pictures as soon as I get a chance so you can see where all of the fuses and relays are located.

These are from an electrical manual for a 94. They should be close...Jimmy
