I purchased an aftermarket rear spoiler with an LED 3rd brake light in it. I have a 2013 Nissan Altima 2.5 S. I want to disconnect the 3rd brake light in the cabin and just use the one on the spoiler. I cannot seem to find the harness to disconnect the existing and connect the new one. Can you help?
