Where is and how do I access the main fusebox of a 1990 XJS? I found the one under the glove box, but cannot find the main one. Any help appreciated.

Thanks,

In my 1991 there is a second fuse box under the steering wheel. Large headed plastic popper seen when the door is open and also held on by clips. turn (a coin is good) and take out the popper and pull under panel downwards.
