How can I disable the factory alarm. Every time I lock or unlock the car using the key fob or key it

I’m looking at the responses now. I have confirmed it is the horn and not a beep. It is OEM. Everything in the truck is except the motor oil.

 

Is there anyway I could use that diagram to turn his damn horn off? I don’t understand or know how to use any of the instruments. I’m not electronic dude.

 

This is from the manual of my 2013, bought straight from the dealer with the alarm installed from the factory.
1. Start with the LED light switch in the off position, then turn the vehicles ignition key on then off.
2. Within 10 seconds, cycle the LED light switch to on then off three times (Press and release the switch 6 times).
3. If the chirps were off before you started, then you will hear 1 chirp indicating that they have been turned on.
4. If the chirps were on before you started, then you will hear 2 chirps indicating that they have been turn off.

Hope it works for ya.

 

Locate connectors 1I and 1C. The are connected to the Cab Junction/Fuse box.


Identify the pin 22 on 1I and snip, strip and add an insulated female connector to the wire coming from 1I. The other end, strip and crimp a male connector.
Identify the pin 10 on 1C and snip, strip and add an insulated female connector to the wire coming from 1C. The other end, strip and crimp a male connector.
Measure the distance to the cut wires and cut a length of wire to reach. Strip and crimp, on both ends of this wire, a female connector. This wire mates to the cut wires.

It'll by-pass the ECU Alarm ground. If later there's a need to return to how it was, then the cut wires will mate back to the connectors via the female & male connectors added.
