well the way i do it is this: make sure you have plenty or wire first. take your leds and find a spot to hang them in the back of the vent, of course you would have to take them apart and rip into the dash a lil bit. i used silicone. then after you hang them all, you gotta run the wired from the leds to the battery and to the switch. or you could wire the leds to a constant fuse. but if you do that then the leds will be on when ever the car is on. if you have a buddy that can help you out that would be good bc 2 heads work better than one ya know. but i think you could pull it off.
