Use a voltage tester and look for the wires that are hot when the lights in question are turned on. It's not as difficult as you may think.

I believe the brown wires are the parking lights, if I were you I'd still check it with a test light or voltmeter to be sure.

We don't have a clue what year or model of car you drive. There's a good chance that the parking light wire is brown, and you can pick it up in the kick panel if that's easier.
