How to add 2015 Scion Frs Valenti 4th Brake Light?

[JonathanAV95]

I know this isnt perhaps a tutorial but it will contain content that could perhaps help a fellow frs figure out this issue as well. So i purchase this kit on amazon Amazon.com: iJDMTOY OEM Fit LED Rear Bumper Backup Lamps w/ Smoked Lens for Rear Fog Lights or Brake Lights Fits 2013-up Scion FR-S Subaru BRZ: Automotive

I assumed they fit perfectly in a 2015 version since their tutorials correspond to a 2013 model. Now i managed to hook up the light on the rear bumper and push the cable through out the little peep hole. However, once its time to manual connect the cables into the left brake light, i seem to become a hopeless goat.

The above is the tutorial they offered.

Now i realize that my brake light wiring is mainly composed of white colored wires. Not sure which is meant to be yellow or red as indicated on the tutorial.

Here are some pictures of what i did, (Obviously it didnt work)!

The pictures might not be the best looking pictures but i did my best due to the late day ! If you have any questions please ask, i know the colors the cables are so if you can see it ask me. I want to be able to get this figured out as soon as possible! Thank You!
