i came across a tail light harness assembly with the 3rd brake light wiring what id like to know is if this can b replaced on a buick that doesnt have the third brake light ? the harness all looks the same except for the connector thats there for the 3rd brake light thanx
 
It just has to light of course, when you hit the brakes and not light with the turn signals. I believe you can get the 12V directly from the brake-light switch that bumps on the brake pedal.
