My owners manual is wrong anyway. It shows a different style Battery Fuse Box. I have a late 99 so I am probably more like the 2000's.
The data came from the 1999 service CD. FWIW, the difference between DRL and no DRL is on the coil side of the headlight relay. So whether you have DRL or not, the fuses should be the same. The four fuses I mentioned are after the relay (on the contact side). There are 2 relays, one High, One low. Out of the relay is 2 fuses, one for each bulb.
Of course, Ford was constantly tinkering.
7.5 amp is plenty for a single 51 watt (low beam) or 60 Watt (Hi Beam) bulb.
