I have a 2023 Sportage SX (Not Prestige), and I'm trying to install a trailer brake controller. I have completed all the steps except connecting the controller to the brake stop light wire on the brake controller connection. There are five wires in total coming into the connector, one is solid green, one is solid black, one is solid brown, one is white with a black stripe, and one is blue with a black stripe. It is a very tight space and I cannot figure out which wire is the brake stop light. It should only have power when the brake is pressed down. Does anyone know what color wire l'm needing to connect to?
