Ford Mustang IV New Edge 1999-2004 uses a passenger-compartment fuse panel and an under-hood power-distribution box. Some circuits differ by model year, V6/V8 engine, Cobra equipment and Mach 460/Mach 1000 audio.
For the next generation, see Ford Mustang S197 2005-2009. Fuse numbers from the S197 do not carry over to the New Edge.
Fuse-box locations
Passenger compartment: under the dashboard on the driver’s side. Engine compartment: the power-distribution box contains the high-current fuses and relays for starter, cooling fan, fuel pump, ABS, PCM, Cobra and Mach 1000 circuits.

FAQ – Ford Mustang 1999-2004 fuses
Why does under-hood position 15 have two different ratings?
On 1999-2002 cars it is a 10 A radio circuit. On 2003-2004 cars with Mach 1000 it can be a 30 A feed for the left-side amplifiers.
Does the same cooling-fan fuse apply to V6 and V8?
No. Under-hood position 1 is listed as 30 A for V6 and 50 A for V8.
