I just did this, and it lights up the dash and resets when the car is shut off on my 16. I'll have to report back on how I like all nannies off when I autox next weekend. I used a mini toggle switch and kept it under the cupholder, partially for the cleanest look, and partially so I don't get a hair up my *** on a wet road and decide to go a little crazy and end up missing a tree because of it. I know I can crash anyways but turning off all the safeties to intentionally screw around is something I want hidden, I don't trust myself that much haha. Besides the cup holder is very easy to remove.
