Carbon Fiber Diffuser w Rainlight
So I just picked up a carbon diffuser with a rainlight and wanted to know how to wire it to my brake light. Is there a pin out chart for the pre lci f30. The diffuser came with a red yellow and black wire.

Afaik you have to pin this into the left or right main brake light harness to the lamp, red should be the power cord, black is probably ground.
Open the trunk, the backlight cover, put the diffusor into the trunk and test the wires at attaching them to test, wheres the problem?

Black is ground, so plug it to a battery and see if red is constant and yellow flashing or something.
