Mercury Sable (1996-1999) – Fuse Box Diagrams and Relays

Mercury Sable 1996-1999 uses a passenger-compartment fuse panel and an engine-compartment power distribution box. The 1996 under-hood layout differs from the 1997-1999 arrangement, so both are shown separately.

Several circuits also vary by model year inside the cabin panel. The duplicated position 32 is intentional: it is rated 5 A in 1996 and 10 A in 1997-1999.

For the next generation, see Mercury Sable 2000-2005.

FAQ – Mercury Sable 1996-1999 fuses

Why are there separate 1996 and 1997-1999 under-hood tables?

The power distribution box changed after 1996. The physical numbering and relay assignments are not identical.

Where is the cigarette-lighter fuse?

Cabin position 21 – 20 A.

Where is the diagnostic connector fuse?

Cabin position 25 – 10 A supplies the Data Link Connector.

Where is the fuel-pump fuse?

The under-hood fuel-pump circuit is position 10 – 20 A. On the 1997-1999 layout, the fuel-pump relay is position 29.
