The Bentley manual has a good description of this, in the beginning
of the "Electrical Systems - Wiring" section (page 97.2).

Anyway, the fuses are numbered 1 to 15 starting from the left,
corresponding to S1 to S15 in the wiring diagram.  The relay
slots are J, K, L, M and N, also starting from the left, as follows:

J: vacant
K: Load reduction relay
L: Fuel pump relay (remark: this should be bypassed to an external
   location by a recall)
M: Intermittent wiper relay
N: Hazard/turnsignal flasher relay

There are also a number of relays mounted on blocks attached to
the top of the relay/fuse panel but they are not necessarily in
a fixed order.
