The green[common] is also ground so it get connected also to Kia black, or just jumped on the switch

So I wired as stated above. Switch LED is ON until I press the button and the light goes off. Anyway to make that reverse? I consider myself fairly intelligent and the switch came with some instructions but I don't want to screw anything up. It does work though and only took about 15 minutes to do. Huge thank you!

I believe the pink wire is "hot" when VESS is active, and with the above instructions that wire is used directly to power the LED. You would have to add circuitry to do the reverse.

Either way I’m pumped! I appreciate the replies and all your help!
 
Here is the finished product. There are some plastic support ridges in the panel so it only has a few places it could go. I think it came out pretty sharp. Works great and super easy fix! Thanks again.

While this solution is the most elegant thus far, I think putting a switch in place of the fuse is the easiest. (Discussed in other threads) It's $50, but ultimately worth it. No disrespect to the ENirogus who figured all this out.
Well, the fuse shuts off more than the sound, so there is that disadvantage.
 
Cory thanks for posting the pic, very clean install, you would laugh at me, my switch is just hanging around the steering column
 
Looking at this pic from a PHEV owner who successfully retroed the switch, I realize the PHEV has an extra functional switch.
I really need the wiring diagram from the PHEV if anyone has access, or is going to get access it would be helpful

THe idea being that maybe, just maybe, one could retro the switch from the PHEV and with the right rewiring, use the 12 volt battery reset button forthe VESS defeat.

My post #5 the second image 'crash pad switch' is the part of the wiring diagram I would need for the PHEV. It might be the same connector number, or it might differ. IT is in the 'connector view' section of the electrical diagrams section of the shop manual
 
So, going from the images I have of the Niro HEV switch wiring, and the EV schematics, there are 3 pins different between the two.

In the EV there is a red wire coming from a fuse[module 5 IGPM] that also feeds the electrochromic mirror. I cannot see any internal connection to the switches or any reason why it is there.

The HEV has a green wire on pin 13 and a a gray wire on pin 16. One or both of these must be the 12 volt battery switch wire.
All of this assumes without direct proof that the wiring in the switch connector remains otherwise the same. We have a hint because we know thanks to some intrepid HEV owners, that the VESS wiring is the same color in the same location, but this is not assured.
 
For now I was able to reach into the area behind the bumper and unplug the speaker
I'm a bit intimidated by the wiring being discussed here, and unplugging the speaker as described by batmick1 above sounds more my speed. Would greatly appreciate if someone could post instructions as to how the speaker can be unplugged.
 
Perhaps I made it sound more intimidating than it is.
Personally removing the bumper is more daunting to me.
The video linked in the other thread shows removing the bumper pretty well
 
ENirogus, thanks so much for posting this. I got a 2020 Niro EV two weeks ago and the super LOUD reverse sound is really annoying. I will do this mod. I'm sure my neighbors will appreciate it. Even the 'space ship' sound while at low speeds is annoying at times. I really appreciate the work U put into this and for posting the diagrams.
 
Great! Now I don't have to buy the schematic!

I have an idea to put a capacitive touch switch in the panel behind the blank switch. I have found some that should work behind the plastic cover, and maybe also drill a small hole, fill with clear epoxy and get the indicator light to light too.

Looks like they come several at a time so if it works I'll send you one.

I was thinking about using a magnet reed switch
 
So while other countries get a switch to turn off the incredibly reverse chime, and all of VESS, we in the US do not have this option.
Economies of scale being what they are, Kia did not make a different wiring harness for the US cars, so it turns out the wires extend all the way to the 'crash pad' switch assembly, although there is no switch. By examining the factory wiring diagrams, there is a blue with a black stripe wire that runs to the connector that when momentarily grounded, disables the VESS system, until you push it again or turn the vehicle off and on again.

I will put the wiring diagrams at the end as they are only for understanding what is happening.

First you need to pull the crash pad switch panel out.

To do this you need to start with the door aperture trim panel, which will pop out with a trim tool or carefully with a screwdriver. It is retained by the door seal, but you can leave it tucked in View attachment 12205
The two screws seen here backed out need to be removed. The lower panel that contains the fuse box door can be pulled out and down without totally removing it. Then the switch panel can be pulled out, you can get some purchase with your fingers between the steering column area. If you haven't removed newer car trim, it takes a good pull but do be a bit careful
 
Wow. I can’t believe how easy that was. 2021 Niro EV. Everything was exactly as described. I left the button sitting beside the steering column.
 
I would think a competent mechanic or perhaps a stereo installer could do it pretty easily. Perhaps bring a printout of the instructions here
