Here's a pic of the button: Link
. It's the small round one. The up/down switch is for the leds in the floorboard (which I'm probably going to be taking out soon.) The missing plate on the right side was replaced since the pic was taken. haha
Cameron (El Pres) helped me get this setup. Basically you put the key in and turn the car to the ON position (not start). That validates the microchip and everything. Then you can just push the button and it actually starts the car. You have to hold it down for a second the exact same as you turning the key forward to the start position. It's just a wired in connection that when you push the button, it's the exact same as the key touching the connection in the ignition.
Not practical at all, but fun for showing off sometimes.
Just a toy.
Edit: And ever since I got it, I've been meaning to stop by a sign shop and get them to engrave a white "Start" label on the button. I'll do it one day. haha
