CAR WON'T TURN OFF, EMERGENCY, PLEASE HELP... Options

[JoKeRkId613]

As many know by my annoying posts, I've been installing the ST205 cluster on my AT200. Two members have been contributing greatly to this project with their knowledge and even provided me somewhat of a guide. I went over it many times and everything works. Every light works. My temperature needle is insane, but w.e. I'm not worried about that one right now as I pretty much just got a new cooling system, radiator & company. My gas gauge also is on empty which is not accurate. But my main issue now is the car itself. It won't turn off...

The cluster has 3 plugs in the back. The blue plug(the one to the right) is the one with the problem. I know this because when I turn off the car and pull the keys out, the engine stays on. All else turns off properly(cdplayer, windows, etc.). And as soon as I pull the blue plug out, the engine turns off. I mean, that's okay except then I would have to pull my cluster out and yank the blue plug out everytime I turn off the car. Lol. Not too convinient. I noticed the two people that were helping me have manual cars... Mine is auto. I'm not sure if that has anything to do with it but I'm very worried.

If anyone knows what this could be, I would really appreciate some help. Thanks.
