The ****** does not work now. I have opened the cover on the steering wheel to check the wiring from the button It looks odd to me with just a wire to the contact pad without any picture of a closed circuit.

First thing to do is have someone check the clockspring for shorts and opens. The steering wheel must be opened to do this, so it's best to hire a professional. One thing you can do yourself is to look for loose or damaged wires and connectors along the steering column above the driver's feet.
Was Cruise Control working before the New Horn was installed? The power supply to the Horn, (input to ground wire) is connected to the Cruise Control Module (CCM). This CCM is wired to the Relay Switch Box located in the Engine Bay. The Relay Box cover will have a Chart indicating what function each Relay coresponds to. Your local autoparts store (AutoZone) can test the Relay Switch, and you'll know (if any Relay) need to be replaced.
The CCM is also wired to the Steering Wheel, but first passes through the Clock Spring Coil, located just behind the Steering Wheel. The Clock Spring allowes for the Function Buttons on the Steering Wheel to have power while Steering Wheel spins.
The Clock Spring can malfunction or break, its rare, but this will cut power to the Function Buttons on Steering Wheel. If ALL the buttons on Steering Wheel dont work, then the Clock Spring is the Culprit. The Coil may need to be replaced.
The Cruise Control Module itself may have failed and also would cause a few or all Steering Wheel Functions to quit working.
But first check the Relay Switch Box and examine the Harness Cables connecting (Steering Wheel--to--CCM--to--Relay Switch Box--to--Battery Supply).
Also if Cruise Control was working before the new Horn was installed and now not working, then most likely the Problem is a bad wire connection somewhere and/or is a faulty Relay.
You have all the informations to find your problem. jump a wire on connector X4 G1 tan wire to ground and check X1 E5 with a test light or multimeter to see if there is a output, you should have 12 volts. If you dont have any voltage the horn relay is defective. I check in the shop manual and the relay come with the underhood fuse block.
Try removing the fuse for the steering wheel module (swm) with the key on, but the engine off. it will reset the system.
Open the drivers door and look on the end of the dash. There is a cover with a place cut out to put your thumb in. remove the cover and on the backside it has a description of the fuses and positions.
If that doesn't help, it may need a new stalk or could possibly a steering wheel module issue.
Lift the hood and prop it open. Disconnect both battery cables from their terminals. Wait at least three minutes for all residual electricity to discharge before you begin working near the airbag.
2Locate the two airbag attaching screws, one on each side of the steering wheel. Pry off the plastic covers to reveal a Torx screw. Use a Torx screwdriver to loosen these two screws, which you can't remove completely. They will stop when fully retracted and remain attached to the steering wheel.
3Lift the airbag out of the steering wheel. Disconnect the airbag wires from the harness by lifting up the plastic tabs on each side and pulling the two sections apart. Place the airbag face up in a safe location.
4Unplug the horn electrical connector, which you will see once you remove the airbag.
5Point the front wheels straight ahead. Remove the steering wheel retaining nut using a socket. Place a mark on the steering wheel and the steering wheel shaft so you will be able to realign them during reassembly.
6Attach the steering wheel puller. There are bolt holes on each side of the steering wheel shaft. Screw the bolts on the puller into these holes and turn the puller handle clockwise to force the steering wheel off the shaft.
7Remove the steering column covers by detaching the two screws on the front of the column. You will see these once you remove the steering wheel. There is one additional screw under the steering column. Pry off the ignition switch bezel. This is the plastic piece that surrounds the ignition cylinder. You should be able to pull it off using your fingers. If not, use a small flat-head screwdriver.
8Unplug the connector from the ignition switch. This connector simply pulls out of the wiring harness, without any clips to remove.
9Insert the key into the ignition and turn it to the "ACC" position. Insert a small screwdriver into the hole located on the bottom of the ignition switch casing to depress the release button. With the button depressed, use the key to pull the cylinder out of the casing.
Installing the Cylinder
10Insert the key into the new cylinder and turn it to the "ACC" position. Insert the cylinder into the casing. When it seats, you should hear and/or feel a click. Try to pull the cylinder out. If you cannot do so, it is properly seated. Reconnect the ignition switch wire to the wiring harness. Snap the plastic ignition bezel back into place.
11Replace the steering column covers and the three screws.
12Place the steering wheel back over the steering wheel shaft, ensuring that the marks you made earlier are aligned.Turn the handle of the steering wheel puller counterclockwise until the steering wheel is fully seated. Detach the puller. Replace the steering wheel retaining nut.
13Connect the horn wires.
14Connect the airbag wires to the wiring harness and place the airbag into the steering wheel. Tighten the Torx screws on each side of the steering wheel and replace their covers.
get your owners manual out of the glove box and look in the index for fuse panel. now that you know where it is, go there and pull the cover off. the horn relay is a square box plugged into it and will be labeled on the legend in the owners manual and on the back of the panel cover, cheap to replace as one relay fit about every Ford made for 60 years. if that does not do it then you are looking to buy a new horn switch, means taking the plastic cosmetics off the steering wheel. as as it is pre-airbag you do not have that danger to deal with. not hard to do, but where you find that part new is going to keep you googling for a day or two. when all else fails you can mount a momentary single pole push button switch to the dashboard and splice its wires into the horn wires in the wiring bundle on the steering column.
it is not the fuses, if the fuses where blown the radio would not work, this is caused by the rotaqting ribbon contact under the steering wheel having an open circuit, this contact is what allows the wheel to turn but still have a connection to the steering column wiring and the radio..
Todd, If your Air Bag Light is on and your cruise control does not work. Contact me before doing the test procedure below!
Todd, sense you have the steering wheel cover off, we need to check to see if it will honk when you take the ground wire for the horn and ground it anywhere to a good ground, preferably the ground post from the battery. We know this is always a perfect ground! The wire for the horn will be a single wire all by itself. If it doesn't Honk see below.
Next: Next we want to ground the horn wire coming out of the other side of the steering wheel, this is much harder but will tell us what we need to know.
