wiring halo's into parking lights...which wire??

I don't have a clue what vehicle or fixtures you have but I can tell you that there are a lot of chassis ground fixtures. These don't require a ground wire. If I'm guessing correct, green is left turn and brown is right turn. Yellow is park for both sides. I'm sure you'll finger it out one way or another.

they may go to the turn signal but that would only be cooler if they blink with the turn signal on right? yet still should remain on with the signals not depressed. as the pass side has only 2 wires directly to it. 1 yellow and 1 light brown. i tapped the brown and the hellow brown of each side. so they should blink with the blinker engaged....or so i hope. as that was my intention. just wasnt gonna say it till i poated the vid of it. haha
