Factory Fog Light Switch Question

I was running the wiring harness for my light bar tonight. I purchased a switch from Air on Board to go in the blank factory location to the left of the steering wheel and between the factory Fog Light Switch and the Power Inverter Switch.

I'd like to tap into the illumination wire on the factory Fog switch to light the light bar switch when the dash lights are on.

I can't figure out which is the proper wire to tap though. Can you guys offer any help?

Thanks!

 

Usually its green

 

Usually it’s the green and green with white stripe(or white with green stripe)
They may have changed it but on the older models the dimmer is on the ground side

 

From top to bottom I have black and white striped, blue, green with white stripe, and green.

 

Got it. Bottom green wire. My tap was not good. Respliced and it's working perfectly. Thanks!
