I'd sure like to see a wiring diagram.Yes the speaker unit is up high, if you look from the engine compartment you may be able to see the wires.
Oh man I may have to look into this. Sounds like it might be pretty straightforward to add custom sounds for the earlier models. Just use the control box output as a trigger and play a custom .wav file. I'm interested.There seems to be some variation in the units.... earlier units apparently have a 2 wire connector and are a speaker only, as is the one pictured. In the dash, above the glove box is the control unit and it has a 45 watt amp.
Later units have the connector in the center, as in the video I posted, and are CAN bus devices and the logic is inside the box, and they appear to be mounted higher on the Kia.
I visited your site and looked at the Niro stuff. You are sure making progress. You realize the Niro sounds like an electric train?
I saw some video on the Tesla and the Leaf. They also show really obnoxious noises now. They both have continuous sounds - not beeps. I suspect the db meter averages, which means the beep has to be louder than spec to get the average volume up.So, looks like finding the control wires behind the "missing switch" on the dash is a flop, the wires are not in the harness to support the switch, i.e. even if you bought the switch module with all 4 switches in place, no wires in the harness go to the switch.
