So I got this Si off Craigslist and it's had problems since the day I got it. For one they swapped out the H23 and put in an F22 and then a killswitch that is just hell. I got told that if I took it out, my car wouldn't start. But they had it alligator clipped to a wire they shaved under the dash, then from the clip to the switch then to the battery. My car got to the point to where it wouldnt start.

So traces led to the main relay. Switched the relay out and the switch also. Car wouldn't start, so put the switch back in and wired it differently. Fired right up, I let it idle for about 2 minutes then killed it to see if switch was working. It killed it and then I started it up again and then within like a minute, it died again and now I have no idea what it could be. Please help. Module? Coil?

Like the thing is that the switch somehow controls the whole electrical system or something. Like I have no clue if it should do that or not.
