Hi, I have a 01 Hyundai Elantra that I am trying to connect a wiring harness to.. Can you give me some advice as Im having issues finding the right wires in the tail light area to connect to?

The best way to do your installation is to use a circuit tester, like part # 40376. Starting behind the taillights, use the tester to determine which wire is the left and right turn signal, and the running lights. For the left turn, turn on the left turn signal, and then test the wires to see which one has voltage that is turning on and off, and connect the yellow wire to that. For the right turn, use the same process, only using the green wire.
I have added a link to a video of this being done for a different vehicle, but it will describe the process.
