I can certainly help with that. When we installed a similar system on a 2020 Jeep Gladiator, we found that in the drivers side taillight harness, the yellow wire carries the left turn/left brake lamp circuit, so that's where to attach the yellow wire. The white wire with the gray stripe carries the left side running lamp, which would attach to the brown wire. On the passenger side taillight harness, the green wire carries the right turn/right brake lamp circuit and the white and orange striped wire carries the right running lamp circuit.

I've linked to a video showing a different diode kit being installed. The procedure on your vehicle will be a little different, but you will see where and how to access the taillight wiring harnesses. The actual wiring begins at around the 5:10 mark in the video.

Even though we've identified the correct wire colors, it's still a good idea to use a circuit tester like # PTW2993 to positively identify each wire's function as shown in the video.
