Default Fog light install; no power

Anyone had problems with their fog lights not powering up? I got the eye iJDMtoys fogs a while back and when I put them in today I don't see any power at the green wire like the instructions say. after I tapped it I took it back apart and checked for power and I have nothing at the green wire but my headlights and daytime running all work.
I've moved the ground to a couple different locations cleaned it thoroughly that's not the problem. checked and rechecked for power and get nothing at the green wire. Any ideas?

pulled it apart again today. Green wire has no power but will ohm out so i can only assume its a ground. So not sure where Im supposed to get power from, but once i have power this mess will easily be done.

Anyone have a wiring diagram for the headlight harness?

I think ur green wire is ur high beam wire try to turn ur high beam and see if it have power. there is two green wires that's why I asked if you got the wrong one. ground wire is the white/black wire. sorry cant give u the whole wire diagram cause its very long I used my phone to take a pic of the headlight wire diagram for you. the wires should be on the driver side

I wonder why they tell you to tap that wire if that's not it. And I think there are about 4 green wires, but only one is about 18ga and the others are like 24ga.

I got it figured out. I tested the pins on the headlight connector with power on and it was one of the 3 small green wires not the large green wire has the instructions state.

thing is there are 4 green wires, 2 would be easy to tell apart especially if they were different sizes. But there ar 3 of the same color and size.

most of the time the wires will be the same size, you have to check for power for each wire to find out which is which or follow the connector.

I just wish the instructions didn't say use the thick green wire. Or else I would have started the process where I ended it instead of just tapping the thick green wire.
