Thanks for the question. Is there a reason that you would like the hold button disconnected?
I understand the thought that this button is used for towing, but this is a common misunderstanding. I agree that this should not be used for towing as it is a small 4-cylinder vehicle, but the hold button is meant for when you are descending a mountain that will hold it in a certain gear so that you don't have to ride the brakes which overheats them and causes them to fail.
I am attaching the wiring diagram below that will show the lamp and switch circuit. If you want it disconnected, I would just unplug the button from the shifter. This may cause the check engine light to come on, but I am not sure it will.
Take a look at this info and let us know what questions you have.
Thanks
