I already installed mine more than a year ago. The button is from Pivot Racing, I cut the black wire from the IGN sw and tied it to one terminal of the start button. The other one went to a "hot with key on" line at the fuse block and I think it was a pink wire. I also made the illuminating blink with the key on and extinguish when the motor was running. I used the hole thingie on the right side of the steering column, and it's convenient there coz I turn the key on and poke the button. By the time I get my seatbelt on, the engine is already started. Here's what it looks like.
