I used the ash tray door take the tray out plenty of room to wire three toggel switches i will try to get a picture
I put mine in the knee bolster, down and to the right of the steering wheel. I used the flat style of rocker switch instead of a regular toggle switch that would stick out.

You can use the area on the dash between your heated seat buttons. I do not have heated seats and that is where I have four switches located.
I like that.The previous owner put this together, but he said that it was based off the heated seat switch plate that you currently have. My truck came with the factory cubby hole in that spot.
