How to install switch in blank space above cup holders

Hey guys. I searched and came up with how to mount a switch on one of the blank spaces on left of sterring wheel, but not the center ones by cup holders.

I am receiving my retrofits from RAD soon and am installing a switch for the Halos. My preference was center blanks. Anyone recall a write up on using these for any projects on here? I couldnt find one. Never took dash apart, or ran wire from engine bay into cab. Thanks.

 

The link below is one approach. I just pulled the switch blanks and fished the wires around.

Mod Day. Mod 2. Installing power point in center console -clean look, LOTS OF PICS-

 

Great, thank you!
