Adding a chirp to a Hyundai Santa Fe

I'm a newbie here and I must say this is a great site, very informative.
I've search the site and did not come up with any possible answer to my problem although some were close to what I am trying to do. Therefore I am requesting if anyone might have a direct solution to this problem.
I own a 2002 Hyundai Santa Fe suv. The suv is in its 3rd model year. The suv comes with a keyless entry system on all three model years (2001, 2002  and 2003) The only difference is that the pre 2003 models do not chirp (beep) when arming or disarming the security system, only the lights flash. The 2003s' do chirp. My question, is there a way to make the system chirp on pre 2003 models by using relays triggered by the signal that is sent to the door locks or overhead cabin lights (that turn off after a few seconds). I know that the whole system is controlled by the ETACS (Electronic Time and Alarm Control system) module. I've looked on the Hyundai webtech site https://www.hmaservice.com/webtech/ as well as the electrical manual and there is no indication of doing so. But being that the FOB (key transmitter) sends the signal to the ETACS which in turn sends the appropiate signal to the lights, doors etc. Could it be possible to add a relay after the wires that lead from the ETACS to the doors or lights to the horns.
Also I recently added aftermarket horns to replace the low sounding stock ones, and the stock ones are disconnected from the wiring harness. Could it be possible to wire the stock ones to make that chirp? The stock ones have just two wires ( a + blue and a - red). I believe if I were to place a relay it would not make the horn sound continously, but I might be wrong in this assumption. Any suggestions?

Any additional info if needed feel free to ask, and any info given would be highly appreciated.
