Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

Has the cruise stopped working since you put them in? Did the fuse test good? Also is there any DTC / Check engine light / system errors with the truck right now?

The connector for the cruise relay under the hood will be labeled.

Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help.

Both systems are related through the clock spring. That's a wound-up ribbon cable in a plastic housing under the steering wheel. If the cable is breaking, eventually the horn will also stop working.

Have you done any testing? What about the cruise fuse, check the fuse and check for voltage. Any trouble codes for the cruise control. Some of the national brand autostores will check codes for free. To check codes yourself, at the least, you need an obd2 code reader. Hate to see you replace something then find out that didn't fix it.

As far as removing the multifunction switch, there are safety issues because of the airbag. You will have to disarm the airbag and safely remove. Safety is your responsibility. You will have to remove steering wheel, usually requires a puller.
Disable the sir system/airbag.
Remove the steering wheel.
Remove the upper and lower steering column trim covers.
The abrasive sleeve located on the steering column wire harness assemble must be reinstalled. Make note of what connector is coming out of the abrasive sleeve for install purposes.
Remove the wire harness assembly 1 from the wire harness 2.
Dosconnect the turn signal and multifunction switch assembly connector from the sir system coil connector.
Slide the 2 connectors of the turn signal and multifunction switch assembly out of the bulkhead connector 1.
Remove the 2 panhead tapping screws 1 and 3 from the turn signal and multifunction switch assembly 2.
Remove the turn signal and multifunction switch assembly 2 from the steering column tilt head assembly.

The cruise will require input form the wheel speed sensor, you will need to get this sorted first.

Do you have voltage at the cruise module on the other wires when you activate different functions on the switch
