Yeah it was a 3 wire install, well actually 5, ground and e-brake safety (optional), just tap the red, green, and purple wire from the ignition on the steering column,

So far the car stays on until whatever time the turbo timer says is gonna stay on and then turns off when the time's up, I can even lock the car and roll up the windows and stuff and the car keep runing just fine, hope this can help
