Help! GCS 4th brake light on a 2017 Toyota 86!
 

Hey what's up guys! I just bought a GCS 4th brake light and doesn't want to turn on! I was wondering if someone knows what wire goes with what wire! I saw the video on YouTube but it still doesn't want to turn on! Thanks everyone!

I know this is a month old but did you ever figure out how to get it working? I'm having this same problem right now. Only the reverse lighting currently works.

For anyone having the same issue in the future, it's the little red wire connectors. Mine were Not applying enough pressure to penetrate the wire. Fixed that problem by soldering the wiring into the car.
