Installing spoiler with third brake light.
 

I am about to install my spoiler at my friends house. I wanted to know if anyone has any tips on installing the brake lights? All I know is I need to find the wires for the original brake lights.

Ill probably get a professional to do it just checking if anyone can help me. thanks :hello:

The wiring is already there. Once you get the trunk liner off you'll find it pretty easily
