740 Fuse Blowing Consistently

[Jay Epstein]

My '88 740 wagon's #22 (15 amp) fuse lasts about 4-5 days, then it's
toast. This is for:
Buckle lamps
RH park & tail lamps
Tunnel box lams
Relay aux lamps
R H D Instrument
RH Panel lamps

Any ideas on where to start to trace this problem? That's an awful lot
of wiring on which to use a circuit tester . . .

Start where there's motion. The lights for the seat belt buckles run in
a harness that flexes and can wear through beside the seat.
