if this is for your mini max you tap in to one of the fuses in your fuse box under the hood, i can't remember exactly what one it is id have to go look. as far as i remember thats the only place that you need to plug in to
i tapped onto the fuse panel under the hood. Fuse 52 i believe, its for the ECM. so now everytime you turn the key it turns on and shuts off respectively
