For anyone interested in doing the replacement themselves, here is a copy of the instructions from Ford...
This program involves performing an inspection procedure to determine which repairs to the speed control system must be performed; either installation of a fused jumper harness or replacement of the speed control deactivation switch. A flow chart has been developed to direct you to the proper service actions.
NOTE: Disconnecting the battery is no longer required when performing these repairs.
INSPECTION - ALL AFFECTED VEHICLES
1. Disconnect the speed control deactivation switch located on the brake master cylinder and inspect the harness connector for the presence of brake fluid. See Figure 1.
a. If no brake fluid is present, install the fused jumper harness (Labor Operation D).
b. If brake fluid is present, disconnect the speed control servo and inspect the vehicle harness connector for heat damage. See Figure 2.
c. If no heat damage is found at the speed control servo connector (even if there is presence of brake fluid in the connector), proceed to Labor Operation E.
d. If the speed control servo connector is heat damaged, call the Special Service Support Center for further instructions.
LABOR OPERATION D - APPLIES TO VEHICLES WITH NON-LEAKING SWITCHES
1.a. Connect the fused jumper harness (14A411) to the speed control deactivation switch and the vehicle harness.
b. Position the harness alongside the existing harness, located below the master cylinder, so that the fuse holder is higher than the rest of the jumper harness. This will cause any water that enters the engine compartment and gets on the jumper harness to run downhill away from the fuse holder.
c. Secure the jumper to the existing harness with tie straps, making sure the fuse holder is positioned vertically with the cap facing upwards. Wrap the tie straps underneath, then over the top of the existing harness and verify proper fuse holder orientation.
2. Release the vehicle.
LABOR OPERATION E - APPLIES TO VEHICLES WITH LEAKING SWITCHES
1. Remove the speed control deactivation switch from the brake master cylinder. CAUTION: Do not allow any foreign material to enter the master cylinder port once the deactivation switch is removed.
2. Add a few drops of MotorCraft High Performance DOT 3 Brake Fluid, PM-1, to the fluid port at the threaded end of the new deactivation switch. CAUTION: DO NOT apply fluid to the electrical connector.
3. Install the new speed control deactivation switch into the master cylinder and tighten to 18 Nm (13 lb-ft).
4. With the speed control servo disconnected, use shop air only to blow the speed control deactivation switch harness electrical connector and the servo connector dry of any trace of brake fluid. DO NOT USE ANY TYPE OF SOLVENT TO CLEAN THE CONNECTORS.
5. Apply Ford Electrical Grease F8AZ-19G208-AA into each cavity of the vehicle harness connector only. It is not necessary to apply grease to the servo side of the connector.
6. Reconnect the servo connector.
7. Install the adapter jumper harness by connecting it to both the deactivation switch and the vehicle harness. Using the provided tie strap, secure the jumper harness to a nearby component such as the speed control cable or another wire harness.
8. Check the brake fluid level in the master cylinder and adjust if necessary.
9. Release the vehicle.
The part numbers are...
Fused jumper harness: 4W1Z-14A411-BC
Replacement switch and adapter harness: 1L1Z-9F924-AA
NOTE: If you do the repair yourself, the truck will NOT show up in Ford's database as having had the recall done.
