Alrighty, here's a circuit that will light the low beams with the high beams on 2001-2004 models using the 2005-2007 headlamp assemblies.
Warning: This circuit cannot be used if your 2001-2004 Escape, Tribute, or Maverick uses any type of daytime running lamp circuit or module.
The relay is a Potter & Brumfield DPST 12V relay, available for $9.84 from Digi-Key:

This relay is sealed, and the lugs can be soldered. You can also mount this relay under the hood near the driver-side headlamp, and run the high beam indicator wire (the green wire in the diagram) to the instrument cluster along the main harness leading into the instument panel area. The black wire is the ground wire, and it must be securely connected to a reliable ground, since it provides the ground side of the wiring for the low beams when the high beams are on.
Here's the diagram:

You'll need to cut the
LIGHT GREEN with BLACK STRIPE wire leading to the C220A connector on the instrument cluster, then connect the wire shown in the diagram to the wire leading to the instrument cluster connector. The other end of the cut wire must be covered and secured in the harness.
Obviously, make sure that the wiring is done
exactly as shown.
Do not use high-wattage headlamp bulbs, because the headlamp wiring will need to be replaced with heavier wiring, and because the factory headlamp relay may not be able to handle the extra current (which may cause the relay contacts to "weld" closed). Use standard H11 (low) and H7 (high) lamps in the 2005-2007 headlamp assemblies.
This circuit will keep the high-beam indicator and fog lamps working correctly.
