Okay, so my friend and I just spent the last 5 hours installing this. Everything works except for the LED on the rear-view mirror. My car is the one without the factory alarm, so do I need to purchase an LED bulb and fit it in or is it basically already idling in there (thereby meaning I did something wrong)?
