Wiring up the spoiler is pretty simple...here are the steps
1. First you want to unplug your battery then open your trunk and locate the brake light bulb right behind the taillights on the left side of the car
2.There are going to be 3 different bulbs, one has a grey casing, and 2 are black. You want to grab the biggest black one.
3. Next you want to splice into the wires the black and the green wires and relay those wires to the spoiler(green to green and black to black)
4. Tape the spliced wires with electrical tape, reconnect you battery and you are done

P.S. You can check if your taillight is working with a 9 volt battery directly.
